this is a toy is called a drinking bad you put a cup of water in front of it and its head dunks into the cop eventually the head bugs off again but then it goes right drinking bad might seem like it could go on forever without an external source of energy powering it as a pet cremation machine and machine because according to one of the reasons that the fast North what are the main goals of thermodynamics describe two processes of the transfer of energy can heat and they're both connected to each other uses heat from work is done on a system it gains he said he just come back to work and what capacity he transferred into energy which is an internal energy is equal to the it's a fundamental but it's not as the first law of thermodynamics heat transfer to the system - W the way turn on or by the system on the system W was negative and it's black find system W is positive change those signs around so it's keeping track of what the positives and negatives means change in internal energy hypnotize meaning is isolated from the rest of the universe is the first law of thermodynamics innovation of energy which principle of physics even that tiny amount means of the motion, continue forever the energy it needs to drive the wagon doing drinking but isn't a perpetual motion machines only energy from the cup of water to power its movements that is filled with a fluid that has a low boiling point so it can easily change from a gas to a liquid and back to preside change in temperature the talk when the bus had dipped into the cop it gets wet it keeps popping back and forth for a while and has liquid partial vacuum in the Hat dad gets heavier and gets back into the water but the Tipping makes bubbles rise to the liquid into the Buzz head spending more liquid into the button and set in the West Wing in starting to cycle or I still need to water for it to do its thing supposed to cut runs out the bus moving basic types of processes has one property is held constant volume pressure temperature heat while the other properties change stations on all these properties of using all kinds of machines especially engines faster a gas is in a rigid container while heat is added I do not see the pressure of the gas will increase in size what is temperature how do you remove heat depression temperature would decrease stuck inside its container and no matter how much he you at the gas doesn't do any walk you just increasing its internal energy but I said bark process is why the pressure is held constant while heat is added or removed usually because they got to move the piston I do I keep temperature increase energy remove heat volume and temperature decrease which means that an isobaric process can do what his wife & Ally episodes in this case the distance the Piston moves the pressure is equal to 4 / area which means the force is equal to pressure times area is the pressure of the gas is the distance I'm almost at the area Pistons the distance it will be equal to the change in the volume of the container for the system does what if you push V hey would you want a Wacom the system and so it's going to take a lot of heat to change none of the heat Reservoir volume of a system is send change very slowly so that the other properties while the temperature stays constant the volume will expand to the system will do what simple W equals P Delta V equation because of pressure does change changes in pressure into account to another difference between if I can I get that will process it is this his temperature is held constant in isothermal process is the change in the internal energy of the system in this case what sound system will be equal to the amount of heat added or vice versa again the equation for the first law of thermodynamics she was a right because the heat of the system isn't changing but the internal energy of the gas will be equal to the negative of the what restaurants that my dad says that he will spontaneously is often described as being hearing disorder of a system bouncing around has a higher entropy than a soul is this Morris's meteorite and sister in real life what's the meaning of interpreting of a decrease in certain situations like gases do sometimes turn into liquid or solid and liquid increases that means the entropy of the environment increase enough to compensate and then some increase in the entropy of the universe the mean while your freezer is putting out heat as it was how cold inside the hate from your freezer is increasing the entropy of your kitchen in the entropy of the ice is decreasing an increase in the entropy of the universe remember that every time you're making ice you're increasing the disorder the universe attendance increase have to do with probability to see what I mean Patricia ceramic mugs in a few of those arrangements what's on at the state where they have a lower entropy still there not supposed to be three hundred pieces of the pieces for Apollo very close together and every way to cut cachaca is another possible way for the molecules inside the pieces to be arranged so when there are so many ways to be spontaneous if you drop them basically have a much higher entropy is related to heat flow because when heat flows between the entropy increases he spontaneously service from Walnut distance to Qdoba if that leads to an increase in entropy which is why this is so bad I keep bumping up and down when the heat goes out of it the gas condenses and it dumps into the water the first and second law of thermodynamics Baden by the first law of thermodynamics and how is the price of volumetric isobaric isothermal and adiabatic processes we will pay tolls by the second law of Thermodynamics and entropy PBS digital Studios you can head over to my channel check out the playlist of the latest episode from shows like the good stuff Raincross and physics go there with the help of these amazing people and are equally amazing graphic team is Soul
