Unformatted text preview: 35 MPa. For this composite compute (a) longitudinal tensile strength and (b) the longitudinal modulus of elasticity. 2. Estimate the energy required to raise the temperature of 5 kg of aluminum materials from 20 to 150 o C. Specific heat of aluminum is 900 J/kg-K. 3. Heat capacity is a property that is indicative of a materials ability to absorb heat from the external surroundings; it represents the amount of energy required to produce a unit temperature rise. TRUE / FALSE 4. The heat capacity of solids increases/decreases (circle correct answer) with temperature up to the Debye temperature above which it decreases with temperature.
