The specific heat of Pyrex glass is 0.78 J g-1 °C-1. Calculate the heat, q, required when 1.15 g of glass is heated from  34 °C to 65 °C . Give your answer in J with 2 significant figures. Do not include units.

The energy needed to increase the temperature of 0.7 kg of glass by 30 °C was 16 632 J.Calculate the specific heat capacity of glass._________ J/kg°CYou do not need to include units in your answer.

A 100 g glass container is at 10.0 °C. 200 g of water at 90.0 °C is added to the glass container. What is the final temperature of the water and the glass, in °C? (specific heat of water = 1.00 cal/g °C, specific heat of glass = 0.200 cal/g °C)

A 44.0g sample of glass, which has a specific heat capacity of 0.670·J·g−1°C−1, is dropped into an insulated container containing 200.0g of water at 65.0°C and a constant pressure of 1atm. The initial temperature of the glass is 8.2°C.Assuming no heat is absorbed from or by the container, or the surroundings, calculate the equilibrium temperature of the water. Be sure your answer has the correct number of significant digits.

A glass of mass 65.0 g contains 330 g of water. The glass and water are in thermal equilibrium at 25.0 ℃.Calculate the minimum mass of ice at 0.00 ℃ to be added to the glass that will reduce its temperature to 0.00 ℃.Give your answer to an appropriate number of significant figures and with units.Assume that no heat is lost to the surroundings.                specific latent heat of fusion of ice = 3.33 × 105 J kg−1                specific heat capacity of water = 4 200 J kg−1 K−1                specific heat capacity of glass = 510 J kg−1 K−1
