The amount of heat energy in joules required to raise the temperature of 7.40g of water is 526.35 Joules
The amount of energy is expressed according to the formula expressed as:
[tex]E = mc\triangle \theta[/tex]
m is the mass of water = 7.40grams
c is the specific heat of water = 4.184 J/g⁰C
[tex]\triangle \theta = 46 - 29\\ \triangle \theta = 17^0[/tex]
Substitute the given parameters into the formula:
[tex]E = 7.4 \times 17 \times 4.184\\E=526.3472Joules[/tex]
Hence the amount of heat energy in joules required to raise the temperature of 7.40g of water is 526.35 Joules
