Question

Calculate how much heat is absorbed by a sample that weighs 12 kilograms, has a specific heat of 0.231 kg/CJ, and is heated from 45 K to 80 K.

PLEASE ANSWER 20 POINTS

Answer 1

97 J

Step-by-step explanation:

Step 1: Given data

• Mass of the sample (m): 12 kg

• Specific heat capacity (c): 0.231 J/kg.°C (this can also be expressed as 0.231 J/kg.K)

• Initial temperature: 45 K

• Final temperature: 80 K

Step 2: Calculate the temperature change

ΔT = 80 K - 45 K = 35 K

Step 3: Calculate the heat required (Q)

We will use the following expression.

Q = c × m × ΔT

Q = 0.231 J/kg.K × 12 kg × 35 K = 97 J
