A titanium aerospace component has a mass of 2.4 kg.
During a thermal stress test, the component is heated until it reaches a final temperature of 185 ∘C185\text{ }^\circ\text{C}185 ∘C.
The specific heat capacity of titanium is 520 J/kg ∘C520\text{ J/kg }^\circ\text{C}520 J/kg ∘C.
The total thermal energy transferred to the component during the test is 162 240 J162\,240\text{ J}162240 J.
Calculate the temperature of the titanium component before the test began.
