Question

Soil has a specific heat capacity of 1.700J/g C. During the day, the temperature of soil in a

flowerpot increased from 15.6°C to 35.5°C. If the energy from the sun was calculated to be 251 175J,
what was the mass of the soil? Show your work.

Answer 1

m = 7.42 kg

Step-by-step explanation:

Given that,

The specific heat of the soil, c = 1.700J/g C

The temperature of soil in a flowerpot increased from 15.6°C to 35.5°C.

The energy released from the Sun is 251175 J. We need to find the mass of the soil.

We know that,

`Q=mc\Delta T\\\\or\\\\m=(Q)/(c\Delta T)\\\\m=(251175)/(1.7* (35.5-15.6))\\\\m=7424.62\ g`

or

m = 7.42 kg

So, the mass of the soil is equal to 7.42 kg.
