The energy needed to heat 5.95 g of water is 1484.406 J.
When work is done and heat and light are produced, energy is the quantitative quality that is transferred to the body or to the physical system.
The water is heated from 5.5° C to 64.9° C.
The mass of the water is 5.95 grams.
The specific heat of water is 4.2 J g⁻¹ C⁻¹ .
Now, the water is heated from:
T₁ = 5.5° C to T₂ = 64.9° C
Therefore, ΔT = T₂ - T₁ = 64.9 - 5.5 = 59.4° C
The heat energy is given as:
Q = m × C × ΔT
Q = (5.95 g ) × ( 4.2 J g⁻¹ C⁻¹ ) × ( 59.4° C )
Q = 1484.406 J
The energy released on heating 5.95 g of water from 5.5° C to 64.9° C is 1484.406 J.
