Answer:
Mass of iron block is 2 kg
Explanation:
We are given;
- Specific heat of Iron as 450 J/kg/K
- Change in temperature as 3 K
- Heat Energy as 2700 Joules
We are required to determine the mass of iron
To answer the question, we will consider the formula;
Heat energy = Mass × specific heat × Change in temperature
In this case;
Mass = Heat energy ÷ (specific heat × change in temperature)
Therefore;
Mass of Iron block = 2700 Joules ÷ (450 J/kg/K × 3 K)
= 2 kg
Therefore, the mass of iron block is 2 kg
