Answer:
Energy = 0.25 kilowatt-hour
Explanation:
Given the following data;
Power = 25 Watts
Time = 10 hours
Power can be defined as the energy required to do work per unit time.
Mathematically, it is given by the formula;
To find the energy consumed;
Energy = power * time
Substituting into the formula, we have;
Energy = 25 * 10
Energy = 250 Watt-hour
To convert to kilowatt-hour, we would divide by 1000;
Energy = 250/1000
Energy = 0.25 kilowatt-hour
Answer:
3.78075x10^6 kg x meter^2/ second^2
Explanation:
Kinetic energy K= 1/2 x mass x velocity^2
The statement that describes the energy changes associated with evaporation and boiling is that atoms gain energy during evaporation and boiling.
<h3>What is evaporation?</h3>
Evaporation is defined as process by which a solution changes from its liquid state to gaseous state.
Boiling is defined as the heating of water to a point that the vapor pressure is equal to the pressure of the gas above it.
In both phase transition stages, the molecules gain enough energy to change its state to another state.
