Front 1

Define the Latent Heat of Fusion of a Solid.

Back 1

Latent Heat of Fusion of a Solid is the quantity of heat energy required to change it from the solid state to the liquid state without any temperature change.

Front 2

Define Specific Heat capacity.

Back 2

Specific Heat Capacity of a substance is defined as the quantity of heat energy required to raise the temperature of 1 kilogram of a substance by 1 degree.

Front 3

Define Latent Heat of Vaporisation of a Liquid.

Back 3

Latent Heat of Vaporisation of a Liquid is the quantity of heat energy required to change it from the liquid state to the gaseous state without any temperature change.

Front 4

Define the "Heat Capacity" of a substance.

Back 4

The Heat Capacity of a substance is defined as the quantity of heat energy required to raise the temperature of a substance by 1 degree.

Front 5

Define a Cooling Curve.

Back 5

A Cooling Curve is a graph of temperature plotted against time, that denotes how a completely molten substance gradually loses heat to its surroundings with time as it resolidifies.

Front 10

Define the Linear Expansion of a solid.

Back 10

Linear Expansion of a solid is defined as the fractional increase in the length of a solid material per unit increase in temperature.

Front 11

Define the Cubical Expansion of a substance

Back 11

Cubical Expansion of a substance is defined as the fractional increase in the volume of a solid, liquid or gas per unit increase in temperature.

Front 12

Define Temperature.

Back 12

Temperature is defined as a measure of how hot or cold a substance is.

Front 13

Define Heat

Back 13

Heat is defined as a form of energy which is transferred from one body or system to another as a result of a difference in temperature in the body or systems involved.

Front 14

Define Osmosis

Back 14

Osmosis is defined as the diffusion of water molecules or any solvent from a region of high concentration to a region of low concentration through a semi-permeable membrane until an even distribution of water molecules is achieved.

Front 15

Give the formula that denotes the relationship between the, Heat capacity and Specific heat Capacity.

State Boyles Law of Gases.

Back 17

Boyles laws states that the volume of a fixed mass of gas is inversely proportional to its pressure, provided that its temperature is kept constant.

Front 18

State Charles Law of Gases

Back 18

Charles Law states that the volume of a fixed mass of gas is directly proportional to the absolute temperature provided its pressure is kept constant.
