1) Two liquids, A and B, are mixed together, and the resulting temp is 22C. If liquid A has mass m and was initially at temp 35C, and liquid B has mass 3m and was initially at temp 11C, cacluatle the ratio of the specific heats of A divided by B.

2) If the heat capacities of both ice and steam are 0.5 cal/g C, the quantitiy of heat required to change 1 g of ice at -10C to steam at 120C is approximately?

3) An ideal gas is initially at 50C and pressure p1=250kPa occupies a volume V1= 4.5L. It undergoes quasistatic, isothermal expansion until its pressure is reduced to 150kPa. How much work was done by the gas during this process?

R=8.314 J/mol K= 8.206 L atm/ mol k
