How much heat energy is required to raise the temperature of 386 grams of aluminum from 24.0°C to 100.0°C?

26.314KJ

Explanation:

The specific heat capacity formula is : Δ, where Q is the heat energy, m is the mass, c is the heat capacity of the material, and delta T is the change in temperature.

We know from the question that m = 386grams and delta T = 100.0°C - 24.0°C = 76.0°C. From a simple search, we know the specific heat capacity of aluminum = 0.897J/g°C (this changes a little bit depends on the website you use, but the value should be very similar). Let's apply the formula:

Δ

Round according to your teacher's specification (example: significant figures) if needed.

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.
