Study Pack | Accurate & Verified Answers |
A+ Verified
• Define the `Specific Heat Capacity` of a substance. -✓✓The amount
needed to raise the temperature of 1kg of a substance by 1°C
• State the units for Specific Heat Capacity. -✓✓J/°C/kg J
(Joules/Degree Celsius/Kilogram)
• What is the definition of `Power`? -✓✓The rate at which energy is
transferred (the rate at which work is done).
• What is the unit of Power? -✓✓Watts (W)
• Examples of chemical energy stores. -✓✓food, fuel, batteries
• State 4 different stores of energy. -✓✓1. Kinetic Energy
2. Gravitational Potential Energy
3. Elastic Potential Energy
4. Chemical Energy
, • 4.1.2 - Conservation and Dissipation of Energy -✓✓
• State the law of energy conservation -✓✓Energy cannot be created
or destroyed (it can only be transferred into different forms).
• What is waste energy? -✓✓The energy that is not used by the device
for its desired purpose.
• Describe the energy changes that occur to a filament light-bulb -✓✓-
Electrical energy is transferred into heat and light energy
- Light is a useful energy form, heat is a waste energy
• How can the efficiency of a system be increased? -✓✓1. Reducing
waste output (by lubrication, thermal insulation etc.)
2. Recycling waste output (eg. recycling thermal waste energy as input
energy)
• State the consequence for energy transfer of a material with a high
thermal conductivity. -✓✓The rate of energy transfer through the
material is higher than for a material with a lower thermal conductivity.
• What key factors affect the rate of cooling of a building -✓✓- The
thickness of the walls
- The thermal conductivity of the walls
