At 298 K and 1 bar pressure, the density of water is 0.9970 g cm 3 ,

Question:

At 298 K and 1 bar pressure, the density of water is 0.9970 g cm⁻³, and C_P,m = 75.3 J K^-1 mol^-1. The change in volume with temperature is given by ΔV = V_i βΔT, where β, the coefficient of thermal expansion, is 2.07 × 10⁻⁴ K⁻¹. If the temperature of 325 g of water is increased by 25.5 K, calculate w, q, ΔH, and ΔU.
