3. A substance has a density of 19.3 g/ml. What is the volume of 20.2 g of the substance? Hint: density can be used as a conversions factor

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

From the question we have

We have the final answer as

Hope this helps you

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.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
