AI Thread Summary
It is possible to decrease the temperature of a gas without removing heat through adiabatic processes, where the heat absorbed or released is zero while the temperature changes. The discussion highlights the distinction between temperature and heat, emphasizing that they are related but not the same. Participants acknowledge that raising temperature equates to adding heat, while lowering temperature typically involves heat removal. The concept of adiabatic processes is crucial in understanding how temperature can change without heat transfer. Overall, the thread explores the nuances of thermodynamic principles related to gas behavior.

Is it possible to decrease the temperature of a gas without removing any heat from the gas?

I know if temperature is raised it is an equilvalent to adding heat and if temperature is lovered it is an equilvalent to removing heat.
 
Physics news on Phys.org
yes ofcorse temp. and heat are two different(but not tooo different) things
u do have adiabatic processes in which heat absorbed/released is 0 bet the temp. of the system changes

Thanks, very helpful
 
welcome:cool:
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
