Find the energy required to increase the room temperature of
a coffee in a cup to a temperature of 60°C.
Liquid weighing 0.98 gram and containing 90% of carbon and 8% of hydrogen give the following result in the bomb calorimeter experiment amount of water taken in the calorimeter equal to 450 gram water equivalent of the calorimeter equal
to 450 gram rise in temperature of water equal to 1.8 degree centigrade if the latent heat of steam is 587 calorie per gram calculate the cross and net calorific value of the fuel
6.0 g of cream at 13.2 °C are added to an insulated cup containing 150.0 g of coffee at 92.9 °C. Calculate the equilibrium temperature of the coffee.
You may assume no heat is lost to the cup or surroundings, and that any physical properties of cream and coffee you need are the same as those of water.
Be sure your answer has 3 significant digits.
