How much heat energy is needed to heat 200.0 g of water from 10.0 degrees C to 50.0 degrees C, with 4.184 J/g degreesC

Answer 1

in order to find the energy required to heat the water you need to use the equation q=mcΔT

q=heat/energy in Joules

m=mass in grams

c= heat capacity, given as 4.18J/g°C

ΔT= change in temperature

q=(200)(4.18)(40)= 3.344E4 J=33.44 kJ
