Temperature change of A = i x (temperature change of B)

56.8 Cal to joules

How much energy is evolved as heat when 4.7 L of water at 0 °C solidifies to ice? (The heat of fusion of water is 333 J/g.) Energy evolved = ____J.

A student calibrated a 10-mL graduated cylinder using water. The empty graduated cylinder weighed 24.378 grams. When it was filled with 9.89 mL of deionized water, it weighed 33.826 grams. The temperature of the water was 21.8oC. What is the density of water, based on these measurements?

culate the amount of heat needed to boil 14.1 g of ethanol (CH,CH,OH), beginning from a temperature of 47.6 °C. Round your answer to 3 significant its. Also, be sure your answer contains a unit symbol. Explanation Chack X

Find the final temperature if 5000. J is applied to 45.9 g copper that starts at 16.5 degrees C.

A heat pump is an electrical device that heats a building by pumping heat in from the cold outside. In other words, it's the same as a refrigerator, but its purpose is to warm the hot reservoir rather than to cool the cold reservoir (even though it does both). Let us define the following standard symbols, all taken to be positive by convention:Th = temperature inside buildingTe = temperature outsideQh heat pumped into building in 1 day Qe = heat taken from outdoors in 1 dayW = electrical energy used by heat pump in 1 day Explain why the "coefficient of performance" (COP) for a heat pump should be defined as Qh /W.

If a 33.76 gram piece of porcelain which has a specific heat of 1.07 J/goC absorbs 1,936.56 J of energy, how much did the temperature change?  Round your answer to 2 numbers after the decimal and include the correct units.

what amount of heat in J is required to raise the tempereture of 326.7 g of lead by 13.1 degrees celsius? the specific heat of lead is 0.128 j/g degrees celsius. give answer in standard notation to 0 decimal places
