4.8 g/cm3 with sig figs since it's mass/volume you divide 76 grams by 16 cm3
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.

Put it in a beaker. Use a smaller beaker filled half way with ice and water and place in the larger one. It should be about an inch or two above the mixture. Heat over a Bunsen burner and the naphthalene will deposit on the bottom of smaller beaker.
And in this way, nephthalene be separated from the mixture of KBR and sand.
Heat is needed to change solid to liquid even to gas!
