Heat L1 SCP

If a substance has a higher specific heat capacity what does it mean

• It takes less energy to increase its temperature and takes more time to heat up

• it takes more energy to increase its temperature and takes less time to heat up

• It takes less energy to increase its temperature and takes less time to heat up

• It takes more energy to increase its temperature and it takes more time time to heat up

A bowl of water with 600ml increases its temperature from 24 to 42 degrees. What is the energy required to do this.

c = 4.18 and q = m c t. 2sf with symbol for unit only.no gaps

If trying to protect from radiation (your favourite donut by the pool) You would consider covering it with to reflect radiation. Multi answer.

• Shiny Surface

• Dull Surface

• Dark Surface

• Light Surface

• You should play it safe and eat it

If trying to protect from radiation (your favourite donut by the pool) You are still worried, which is best for absorbing the least radiation - multi answer

• Shiny Surface

• Dull Surface

• Dark Surface

• Light Surface

• I dont like donuts or apostrophes

Silver has a heat capacity of 240 J kg-c-. If you have 20 kg and heat it from 20 degrees to 600 degrees. What is the energy it takes in Kilojoules. q = mct . 4 sf and symbols for units, no gaps

Metal feels cold because it..

• Is cold... obvious really

• conducts cold toward your hand from the metal as metal as a higher specific heat capacity

• Metal is a better conductor and has a lower specific heat capacity, so absorbs energy from your hand making it feel cold

• Metal is a better conductor and has a lower specific heat capacity and so conducts the cold to your hand making it feel cold

• I am worried about the donut that is in the sun now.

What does the horizontal length of melting vs boiling on the graph tell you.

• The specific heat energy is higher for boiling

• The specific heat energy for melting is higher

• The latent energy of fusion is lower than vaporisation

• The latent energy of vaporisation is lower than fusion

What do the vertical gradients on the graph tell you.

• The time it takes to heat.

• The specific heat capacity - steeper is lower

• The specific heat capacity - steeper is higher

• The latent energy of the substance

This is a convection current, key words I must use in discussing. multi answer

• More dense , cold air, falls

• Donuts

• Kinetic energy

• Expands becomes Less dense, lighter air, rises

• Radiation
