HEAT

Form of energy

Heat is the cause; temperature change is the effect

Heat flows from a hotter body to a coller body

Heat exchange takes places till the bodies attain the same temperature.

Measurement

Temperature is a measure of the effect of heat

Celsius, Fahrenheit, Kelvin are common units of temperature

Here is the interconversion formula connecting temperature scales

Thermometers are used to measure temperature

Thermal expansion property of liquid is used in the working of a thermometer

Types of thermometers: Clinical, Digital, Laboratory, & Maximum-Minimum

Mercury or Ethyl Alcohol are used as working substances in most thermometers

Transfer of heat

Conduction

Heat transfer without any actual movement of the particles of material

Mostly in solids

Conductors: Allows the heat easily to pass through. Eg. Metals

Insulators: Poor conductors of heat. Eg. Wood, glass

Uses: Iron box, Cooking vessel

Convection

Heat transfer by actual movement of the particles of material

Mostly in liquids and gases

Hot air rises up and cold air comes down creating a circulation current

Used in air conditioners, ventilators, hot air balloon, land breze, & sea breeze

Radiation

Heat transfer even without a material medium

Themos Flasks

Vauum is used to maintain the temperature

Evacuated chamber to keep hot or cold liquids
