Sixty five grams of ethyl alcohol is heated from 10 degree celsius to 75 degree celsius. how much heat is absorbed in the process?

Answers

Answered by s15555

Answer:

is an intensive property (like density, color, etc.) that does not depend on the amount of a substance present. This allows substances to be identified using their specific heat.

Imagine an unknown metal of known mass is heated to a known temperature. The heated metal can then be placed into a sample of water for which the volume (and therefore mass since 1mL=1g) and temperature are known.

The amount of energy (Q) transferred to the water can be calculated by using the equation

since the mass (m) and ∆T(temp change) can be measured.

This allows for a calculation of the C value for the metal since the head gained (Qw) of the water will equal the heat lost by the metal (Qm).

The C value for the metal allows the metal to be identified.
