Question 1

One gram of water is heated from 0°C to 100°C at a constant pressure of 1 atm. Determine the approximate change in internal energy (in cal) of the water.

◦
160

◦
130

◦
100

◦
180

◦
50


Question 2

Steel blocks A and B, which have equal masses, are at TA = 300 °C and TB = 400 °C. Block C, with mC = 2mA, is at TC = 350 °C. Blocks A and B are placed in contact, isolated, and allowed to come into equilibrium. Then they are placed in contact with block C. At that instant,

◦
TA = TB<TC.

◦
TA = TB = TC.

◦
TA = TB>TC.

◦
TA + TB = TC.

◦
TA−TB = TC.
