You are given 10g samples of each of the materials listed. each material is heated for the same period of time. rank the materials in terms of temperature change observed from least change to most change.

specific heat
material specific heat (j/kg k)
aluminum 900
copper 390
brass 380
silver 230
platinum 130
water 4186

Temperature change observed in following material from least change to most change:

1. Water

2. Aluminium

3. Copper

4. Brass

5. Silver

6. Platinum

Explanation:

The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius.

Higher the specific heat of a material, more the heat is required to change its temperature.

Thus the arrangement of materials in descending order of their specific heat gives us the list of materials with temperature change from least to most.
