Water (2750 g ) is heated until it just begins to boil. If the water absorbs 5.57×105 J of heat in the process, what was the initial temperature of the water?
Water (2850 g) is heated until it just begins to boil. If the water absorbs 5.45*10^5 of heat in the process, what was the initial temperature of the water?
A 50.0 g sample of water, initially at 25.0°C, is heated until it starts to boil. How much heat was needed to heat it to 100.0°C? The specific heat capacity of water is 4.184 J/gC. ( I don't know what formula I would use to solve this.)
4. Calculate the heat change in a system (q) when 12.0 g of water is heated from 20.0 °C to 100.0 °C. 5. A 295 g aluminum engine at an initial temperature of 3.00 °C absorbs 85.0 kJ of heat. What is the final temperature of the engine? The specific heat capacity for aluminum is 0.900 J/(g K).
5. A 79 g sample of water at 21°C is heated until it becomes steam with a temperature of 143°С. Find the change in heat content of the system.

A 130.0 g piece of copper (specific heat 0.38 J/g・°C) is heated and then placed into 400.0 g of water initially at 20.7°C. The water increases in temperature to 22.2°C. What is the initial temperature of the copper? (The specific heat of water is 4.18 J/g・°C and the density of water is 1.00 g/mL).
Suppose a boil water notice is sent out advising all residents in the area to boil their water before drinking it or using it for cooking. You need to boil 12.5 L of water using your natural gas (primarily methane) stove. What volume of natural gas is needed to boil the water if only 14.6% of the heat generated goes towards heating the water. Assume the density of methane is 0.668 g/L, the density of water is 1.00 g/mL, and...
