Thermal properties and temperature — practice question

A beaker holds $0.500\,\text{kg}$ of water at a temperature of $3.0^{\circ}\text{C}$. The beaker is then heated, so the water’s internal energy rises by $21.0\,\text{kJ}$. The specific heat capacity of water is $4200\,\text{J\,kg}^{-1}\,^{\circ}\text{C}^{-1}$. Determine the temperature of the water after heating.

  • A$5.5^{\circ}\text{C}$
  • B$10.0^{\circ}\text{C}$
  • C$13.0^{\circ}\text{C}$
  • D$31.5^{\circ}\text{C}$
