A block of aluminum at 204°C is put into 1.00 kg of water at
24.0°C. They come to equilibrium
at 28.5°C. What was the mass of
the aluminum block?
Aluminum
Water
c = 900 J/(kg*C)
c = 4186 J/(kg*C)
(Unit = kg)

Argon is adiabatically compressed from an initial volume of 16 liters to a final volume of 2 liters. by what factor do the following quantities change? do they increase or decrease? (a) the rms speed (b) the thermal energy of the gas (c) the molar specific heat cv (d) the pressure

(a) if the pressure in gas is doubled while its volume is held constant, by what factor do (i) vrms and (ii) change? (b) is it possible to boil water at room temperature (20oc) without heating it? explain.
