Questions in this deck

01How do you convert °C to kelvins?

T(K) = T(°C) + 273.15.

02What is the ideal gas equation?

PV = nRT.

03What is ΔU for an isothermal ideal-gas process?

ΔU = 0 because internal energy depends only on temperature.

04What P–V relation holds for reversible isothermal compression of an ideal gas?

PV = constant.

05What does adiabatic mean for heat transfer?

Q = 0: no heat is exchanged with the surroundings.

06If W is work received by the system, what is the first law?

ΔU = Q + W. State the sign convention explicitly.
