According to the chart of specific heats, which material requires the most heat to raise its temperature from 10°C to 30°C?
myrzilka [38]

The material which requires the most heat to raise its temperature from 10°C to 30°C is oil.

<h3>What is the formula to calculate absorbed heat?</h3>

The formula which we used to calculate the amount of involved heat in relation with specific heat is:

Q = mcΔT, where

  • Q = absorbed heat
  • m = mass
  • c = specific heat
  • ΔT = change in temperature

Among the given materials, specific heat of oil is highest than other materials so will require maximum absorbed heat.

Hence, oil requires the most heat.
