Question

Imagine you have 1 kg each of iron, glass, and water, and all three samples are at 10°C. Rank the samples from least to greatest amount of energy transferred by heat if each sample increases in temperature by 20°C.rank from 1 the least and 3 the greatest please

Answer 1

Answer:

(From the least to the greatest) Glass < Iron < Water

Explanation:

The greater the specific heat of the material, the greater the amount of heat needed to increase temperature. Specific heats of each material are presented below:

Iron (Rank 2)

$450\,\frac{J}{kg\cdot K}$

Glass (Rank 1)

$0.8\,\frac{J}{kg\cdot K}$

Water (Rank 3)

$4186\,\frac{J}{kg\cdot K}$
