Thermal equilibrium — practice question

(a)[1]

Explain what is meant when two bodies are described as being in thermal equilibrium.

(b(i))[1]

Suggest a thermometer type that is suitable for measuring the temperature of the flame of a Bunsen burner.

(b(ii))[1]

Suggest a thermometer type that would be suitable for measuring the temperature change of a small crystal when it is exposed to a pulse of ultrasound energy.

(c(i))[1]

Water is heated so that its temperature rises from $26.5^\circ\text{C}$ to $38.0^\circ\text{C}$. State, to an appropriate number of decimal places, the temperature change in kelvin.

(c(ii))[1]

State, to an appropriate number of decimal places, the final temperature in kelvin.
