Question

Calculate the energy required to heat 0.30kg of ethanol from 1.0°c to 11.8°c. assume the specific heat capacity of ethanol under these conditions is ·2.44j·g−1k−1 . be sure your answer has the correct number of significant digits.

Answer 1

The energy required to heat 0.30kg of ethanol from 1.0°C to 11.8°C is 7.85 J.

Step-by-step explanation:

To calculate the energy required to heat 0.30kg of ethanol from 1.0°C to 11.8°C, we can use the formula:

Energy = mass * specific heat capacity * temperature change

Plugging in the values, we get:

Energy = 0.30kg * 2.44 J/g-K * (11.8°C - 1.0°C)

Simplifying, we get:

Energy = 0.30kg * 2.44 J/g-K * 10.8°C

Calculating, we get:

Energy = 7.85 J
