Question

A scientist adds heat to each of the following substances. Which will probably absorb the most heat before its temperature changes significantly?

A. 50 g of solid copper
B. 50 g of solid iron
C. 50 g of liquid water
D. 50 g of sand

Answer 1

Answer: Option (C) is the correct answer.

Step-by-step explanation:

Specific heat is defined as the amount of heat necessary to raise the temperature of substance by one degree Celsius.

Mathematically,
`Q = mc \Delta t`

where Q = heat

m = mass of substance

c = specific heat

`\Delta t` = change in temperature

Since mass is same for all the given substances. Therefore, more is the specific heat of a substance more frequently it will raise the temperature.

• Specific heat of copper is 0.385.
• Specific heat of iron is 0.444.
• Specific heat of liquid water is 4.184.
• Specific heat of sand is 0.290.

Thus, we can see that specific heat of liquid water is highest out of the given options.

Hence, we can conclude that liquid water absorb most heat before its temperature changes significantly.

Answer 2

A scientist adds heat to each of the following substances.The one that will probably absorb the most heat before its temperature changes significantly is
50 g of liquid water
because water has larger heat capacity
so correct option is C
hope it help
