Question

Select the statements below that are true when an ice cube is placed in a glass of hot water.Choose one or more:DA qice qwater=B. qwater = -qiceOC. The energy gained by the ice cube will be equal to the energy lost by the water.D. Thermal energy will flow from the ice cube to the water.OE. The energy lost by the ice cube will be equal to the energy gained by the water.F. Thermal energy will be transferred from the water to the ice cube.

Answer 1

In this question, we have a situation where an ice cube is placed in a glass of hot water, which means we have a situation of exothermic and endothermic reactions occurring.

The endothermic reaction will be related to the ice cube, since this cube will increase its temperature, and in order to do that, the cube needs to absorb energy, and this thermal energy will come from the hot water

The exothermic reaction is the hot water releasing this thermal energy to its surroundings, and then the temperature will decrease as well

The options that are the answers will be:

C

F

Letter B should be the opposite, -qwater = qice, and letter A doesn't show the positive or negative sign
