Calculate the amount of heat necessary to raise the temperature of 135.0 g of water from 50.4^$\circ$F to 85.0^$\circ$F. The specific heat of water = 4.184 J/g·^$\circ$C.

To calculate the heat (q) required to raise the temperature of water, use the formula q = m*c*ΔT, where m = mass of water (135.0 g), c = specific heat of water (4.184 J/g°C), and ΔT = change in temperature (85.0°F - 50.4°F = 34.6°F). Since the specific heat is given in J/g°C, we need to convert the temperature change from °F to °C. The conversion factor is (5/9), so ΔT in °C = 34.6°F * (5/9) ≈ 19.22°C. Thus, q = 135.0 g * 4.184 J/g°C * 19.22°C ≈ 10862.5 J or 10.9 kJ.
