AQA Physics Combined - Particle Model of Matter

Which of the following is not a state of matter

• Ice

• Gas

• Liquid

• Solid

Increasing the temperature of a gas increases the store of which energy type of the particles?

• Potential Energy

• Chemical Energy

• Kinetic Energy

• Pressure

The amount of energy to raise the temperature of a 1kg of a given substance by 1ºC

• Specific Latent Heat of Fusion

• Specific Latent Heat of Vapourisation

• Specific Heat Capacity

• Activation Energy

Latent Heat of Fusion: The amount of energy required to change the state of 1kg a substance from solid to liquid at fixed _____________

• Quantity

• Heat Energy

• Temperature

• Pressure

You need a piece of paper and calculator here. You have 2 minutes. Rearrange the equation carefully!

Find how much Ice will melt if you provide 14 000 000 J to a block of ice at 0º C. Latent heat of fusion of ice is 334 kJ / kg

E = m L_f

• about 42 000 kg

• about 4.7 x 10 ^ 9 grams

• about 42 kg

• 0.0238 kg

Find the energy required to boil 0.250 kg of water away at 100ºC. The Latent Heat of Vapourisation of water is 2260 KJ / kg.


Watch out for the units here!

 $E=mL_v\$  

 $L_v\ of\ water\ =\ 2260\ kJ\ per\ kg$  

• 565 000 J

• 565 J

• 9040 J

• 9.040 J

At which point does the substance finish boiling

• B

• C

• E

• F

• D

At Which point is the Kinetic Energy Store increasing?
