A student is provided with a thermometer that shows $1\,^{\circ}\text{C}$ in pure melting ice and $101\,^{\circ}\text{C}$ in pure boiling water. She uses it to find the temperature of some water before and after heating. How does the increase in the water’s temperature, worked out from her readings, compare with the true value?
- AIt is $1\,^{\circ}\text{C}$ lower.
- BIt is the same.
- CIt is $1\,^{\circ}\text{C}$ higher.
- DIt is $2\,^{\circ}\text{C}$ higher.
