Question

A glass vessel with an insulating cover with a surface area of (74 + 100) cm? and (74 +15)
mm thick is filled with ice at 0° C and placed in a second vessel maintained at a temperature
of 100° C. Find the mass of the ice that melts per minute when the flow of heat becomes
steady. Latent heat of ice = 3.3 x 105 J/kg and K for glass = 1.0 W/mk.

During a marathon race David uses energy at a rate of 292 W. What volume of body fluid does he lose in the 5.5 hours of the race if 17.0% of the energy goes to the muscle tissue and the rest is used in removing the perspiration from the body. The latent heat of vaporization is 2.41*10^6 J/kg at 37.0°C and density of water is 1000 kg/m3. Answer in cubic meters.
A heavy pot made of copper has a mass of 2.07 kg (including the lid) and is heated in an oven to a temperature of 155 °C. You pour 0.10 kg of water at 25.6 °C into the pot and quickly close the lid so that no steam can escape. We assume that no heat is lost to the surrounding. For copper, Ccopper 390 J/(kg.K) = For water, Cwater = 4190 J/(kg.K), Lv = 2256 kJ/kg, Lƒ = 333 kJ/kg. What is the final mass of steam in the pot? g
A spherical brass shell has an interior volume of 1.55 x10-3 m3. Within this interior volume is a solid steel ball thathas a volume of 5.00 x 10-4 m3.
