IMPORTANT

Complete the table by writing the correct terms from the list in the spaces in the second column. You will have to use each term more than once.

(thermal energy, internal energy, temperature)

Statement Terms or term
increases when an object is supplied with thermal energy  
a measure of the heat of an object  
energy moving from where the temperature is higher to where it is lower  
the sum of all energies of particles of an object.  
a measure of the sum of the average kinetic energy of particles in an object  
tends to spread out from a hot object  
measured using a thermometer  

EASY

IMPORTANT

Compare the internal energy possessed by 1 kg of water at 100 °C and 1 kg of steam at 100 °C.

EASY

IMPORTANT

State how you could increase the internal energy of a liquid.

EASY
Upper Secondary-IGCSE
IMPORTANT

Explain why steam will give a much worse burn than the same volume of water at the same temperature.

EASY
Upper Secondary-IGCSE
IMPORTANT

Explain why squeezing a gas leads to a rise in temperature. 

EASY

IMPORTANT

Figure shows a sparkler. The sparks are burning iron filings, at a temperature of 1000 °C . Explain why these can land on your hand without causing injury, but the steel rod the sparkler is mounted on will burn you very badly if you touch it before it has cooled, despite being at a lower temperature.
