Thermal Energy Transfer

Specific Heat ● Specific Heat - Amount of heat that is needed to raise

Specific Heat ● Specific Heat - Amount of heat that is needed to raise the temperature of 1 kg of some material by 1°C ● Measured in joules per kilogram Kelvin [J/(kg °K)].

Water ● Specific heat of water high because water molecules form strong bonds with

Water ● Specific heat of water high because water molecules form strong bonds with each other.

Transfer of Energy ● Energy can be transferred by: ● 1. Thermal Conduction 2.

Transfer of Energy ● Energy can be transferred by: ● 1. Thermal Conduction 2. Convection 3. Radiation ● ●

Thermal Conduction ● Conduction - transfer of thermal energy by collisions between particles in

Thermal Conduction ● Conduction - transfer of thermal energy by collisions between particles in matter. ● Conduction = touching

• Material which thermal energy doesn’t flow easily

• Material which thermal energy doesn’t flow easily

Thermal Conductors ● Material in which thermal energy flows easily

Thermal Conductors ● Material in which thermal energy flows easily

● Heat moves faster by conduction in solids and liquids than in gases. ●

● Heat moves faster by conduction in solids and liquids than in gases. ● Gases - particles are farther apart – Collisions with other particles occur less frequently than they do in solids or liquids.

Convection ● Convection - transfer of thermal energy by the movement of particles ●

Convection ● Convection - transfer of thermal energy by the movement of particles ● Fluids – gas or liquid

Radiation ● ● ● Almost no matter exists in the space between Earth and

Radiation ● ● ● Almost no matter exists in the space between Earth and the Sun Heat reaches Earth by radiation. Radiation - transfer of energy by electromagnetic waves.

Thermos ● Vacuum - contains almost no matter – ● Prevents heat transfer by

Thermos ● Vacuum - contains almost no matter – ● Prevents heat transfer by conduction or radiation between liquid and air outside of thermos. Coated with aluminum to make each surface highly reflective.

• Particles move and object expands

• Particles move and object expands

• Particles move less and object shrinks

• Particles move less and object shrinks
