What is specific heat capacity?

Energy to raise 1 kg by 1°C or 1K

What are the units for specific heat capacity?

J/kg°C\text{J/kg°C}

What do materials with high specific heat capacity require?

Lots of thermal energy to raise temperature

What is the formula for calculating energy change using specific heat capacity?

E=mcΔTE = mc\Delta T

Kilograms (kg)

In the formula E=mcΔTE = mc\Delta T, what are the units of energy (EE)?

Joules (J)

How can you reduce thermal energy passing from the beaker into the air?

Use an insulator with lower conductivity

How do you ensure all thermal energy passes into the oil?

Ensure the immersion heater is fully submerged

How can you improve the accuracy of temperature readings?

Use an electronic temperature probe

How do you ensure thermal energy spreads through the oil?

Stir the oil
