A foam cooler of negligible mass contains 1.75 kg of water. Ice from a refrigerator at -15°C, is then added to the water in the cooler. When thermal equilibrium has been reached, the total mass of ice in the cooler is 0.778 kg. Assuming no heat
exchange with the surroundings, what mass of ice was added? For water, Lf = 334 x 10^3 J/kg, and for ice, Ci= 2100 J/(kg .K).

What object a collides with object b and bounces back its final momentum is?

What properties of a moving object are used in determining the object's energy of motion

On a hot saturday morning while people are working inside, the air conditioner keeps the temperature inside the building at 22degreesc. at noon the air conditioner is turned off, and the people go home. the temperature outside is a constant 33degreesc for the rest of the afternoon. if the time constant for the building is 4 hr, what will be the temperature inside the building at 4 : 00 font size decreased by 2 upper p . font size decreased by 2 upper m .? at 6 : 00 font size decreased by 2 upper p . font size decreased by 2 upper m .? when will the temperature inside the building reach 24degreesc? 324281
