Questions from David Sang and Darrell Hamilton Solutions for Chapter: Thermal Properties of Matter, Exercise 1: Exercise 10.1 with Hints & Solutions
What is internal energy?

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 |

Compare the internal energy possessed by of water at and of steam at .

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

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

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

Figure shows a sparkler. The sparks are burning iron filings, at a temperature of . 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.
