A0.600-kg piece of metal x is heated to 100â°c and placed in an aluminum can of mass 0.200-kg which contains 0.500 kg of water initially at 17.3â°c. the final equilibrium temperature of the mixture is 20.2â°c, what is the specific heat of metal x? the specific heat of aluminum is 910 j/kg â k.

Yes it would be a physical change.

We first assume that this gas is an ideal gas where it follows the ideal gas equation. the said equation is expressed as: pv = nrt. from this equation, we can predict the changes in the pressure, volume and temperature. if the volume and the temperature of this gas is doubled, then the pressure still stays the same.
