1)Blood can carry excess energy from the interior to the surface of the body, where the energy is dispersed in a number of ways. While a person is exercising 0.3 kg of blood flows to the body's surface and releases 1000 J of energy. The blood arriving at the surface has a temperature of the body's interior, 37.0 oC. Assuming that the blood has the same specific heat capacity as water, determine the temperature of the blood that leaves the surface and returns to the interior.

Number degrees C

2)The block in the drawing has dimensions L0×2L0×3L0,where L0 =0.3 m. The block has a thermal conductivity of 300 J/(s·m·C˚). In drawings A, B, and C, heat is conducted through the block in three different directions; in each case the temperature of the warmer surface is 36 ˚C and that of the cooler surface is 18 ˚C Determine the heat that flows in 4 s for each case.

3)A cylindrical glass of water (H2O) has a radius of 5.73 cm and a height of 13.4 cm. The density of water is 1.00 g/cm3. How many moles of water are contained in the glass?

4)A 0.0466-m3 container is initially evacuated. Then, 7.75 g of water is placed in the container, and, after some time, all of the water evaporates. If the temperature of the water vapor is 432 K, what is its pressure?
