Question 20

During a vacuum chamber test of a spacecraft's thermal protection shield, a component made of a titanium alloy is cooled rapidly. The temperature of the component decreases from 325.0∘C325.0^\circ\text{C}325.0∘C to 145.0∘C145.0^\circ\text{C}145.0∘C, transferring 42.12 kJ42.12\text{ kJ}42.12 kJ of energy to the chamber's cooling system.

Given that the specific heat capacity of the titanium alloy is 520 J/kg ∘C520\text{ J/kg }^\circ\text{C}520 J/kg ∘C, calculate the mass of the component.
