1. In a nuclear reactor 100.0 g of uranium is used for a certain amount of time. afterwards the mass of all the leftover material is 97.1 g. Calculate the amount of energy produced in Joules. (Please show steps for both) Special Relativity 2. A spaceship passes you at a speed of 0.700 c. As it passes by, you quickly measure its length to be 564. m. How long would it appear when at rest?

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
