Final answer:
The amount of heat required to raise the temperature of 500g of water from 20°C to 30°C is 20,920 J, using the specific heat capacity of water of 4.184 J/g °C and the formula Q = m · C · ΔT.
Step-by-step explanation:
To calculate the amount of heat required to raise the temperature of 500g of water from 20°C to 30°C, we use the specific heat formula. The specific heat of water is 4.184 J/g °C. The mass of water is 500g, and the temperature change (ΔT) is 30°C - 20°C, which is 10°C. The equation to determine the heat (Q) is Q = m · C · ΔT.
Using this formula, we get: Q = 500g · 4.184 J/g °C · 10°C. Therefore: Q = 500 · 4.184 · 10, and Q = 20,920 J (joules). This is the heat required to achieve the desired temperature increase.
