An ice-cube tray of negligible mass contains 0.290 kg ofwater at 18.0°C. How much heat must be removed to cool the water to0.00°C and freeze it? Express your answer in joules, calories, and Btu

An aluminum rod 17.400 cm long at 20°C is heated to 100°C. What is its new length? Aluminum has a linear expansion coefficient of 25 × 10-6 K-1   what is the correct formula for this problem

A 60.0-kg runner expends 359 W of power while running a marathon. Assuming 12.5% of the energy is delivered to the muscle tissue and that the excess energy is removed from the body by sweating, determine the volume of bodily fluid (assume it is water) lost per hour. (At 37.0°C the latent heat of vaporization of water is 2.41 ✕ 106 J/kg.) cm3

How much energy is required to raise the temperature of 0.25 kg of water from 20.°C to 80.°C? Answer in J. (What must i do to solve this?)

What is the ratio of the energy required to warm 125 g of Ice (0.0 \deg C) to body temperature (37 \deg C) to warming the same amount of water through the same temperature change? Answer format is the number Eice/Ewater = (2 significant figures) Latent Heat of Fusion of Water: 335, 000 J/kg Specific Heat Capacity of Water: 4186 J/kg/\deg C

Problem 2: 0.4 kg of ice at – 10°C are mixed with 0.2 kg of water at 50°C. The water and ice are mixed in a calorimeter so that no heat escapes the system. The specific heat of ice is c; = 2090 J/(kg.°C), the la- tent heat of fusion of water is Lf = 3.33× 10° J/kg, and the specific heat of water is cu = 4186 J/(kg-°C). (a) What is the final temperature of the system? (b) How many kg of ice remain in the end? (c) How many kg of water remain in the end?

A piece of ice with a mass of 120 g is transferred directly from the freezer at a temperature of 8°C to a polystyrene cup containing 300 g of water at 85°C. Calculate the final temperature of the water. Ignore any heat lost to the cup and its surroundings. 14.
