A student has a thermometer that shows $1^\u0006\text{C}$ in pure melting ice and $101^\u0006\text{C}$ in pure boiling water. She uses it to find the temperature of some water before it is heated and again after heating. How does the temperature increase obtained from her readings compare with the correct value?
- AIt is $1^\text{C}$ lower.
- BIt is the same.
- CIt is $1^\text{C}$ higher.
- DIt is $2^\text{C}$ higher.
