Assume 150. grams of water is cooled in a refrigerator. The water’s temperature changes from 20.0 C to 12.5 C. The specific heat of water is 4.184J(g·C) 1) Determine the amount of energy in joules transferred by the water.

2) How many calories were transferred?

3) Was this an endothermic process or an exothermic process? Explain

If we compare and contrast electromagnetic waves with sound waves, all but one statement is true. that is a) sound waves require a medium to travel while electromagnetic waves do not. b) electromagnetic waves can travel through the vacuum of space while sound waves cannot. c) electromagnetic waves must have a medium in which to travel, but sound waves can travel anywhere. eliminate d) sound waves must bounce off of matter in order to travel while electromagnetic waves do not require matter to be present.

What statement goes against the kinetic theory of gases
