If the coefficient of volume expansion of brass is 6 10⁻⁵ ^ C ⁻¹ , then fractional change in its density for a 60^ C rise in temperature will be

Step-by-step solution

Density at temperature T is given by aligned & = ₀(1- T) & = ₀- ₀ T - ₀ ₀ & =- T aligned Fractional change in density, aligned & ₀ =- T=-6 10⁻⁵ 60 & ₀ =-3.6 10⁻³ aligned Note: Negative sign indicates that density decreases with rise in temperature.
