A cube has a mass of 100 grams and its density is determined to be 1 g/cm3. The volume of the cube must be . 0.1 cm3 1 cm3 10 cm3 100 cm3

  The volume of the block will be

Explanation:

Density is defined as the mass contained per unit volume.

Given : Mass of cube = 100 grams

Density of cube =

Putting in the values we get:

 Thus volume of the block will be

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.

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?
