Solution

The correct option is D $100 J / k g \cdot^{o} C$
We know that $Q = m s Δ T$
So, the specific heat, $s = \frac{Q}{m Δ T} = \frac{2000}{10 \times 2} = 100 J / k g^{o} C$ .
Thus, the correct option will be D.

Calculate the specific heat of the material if material of 10 kilograms raises temperature 2oC when 2000 joules of heat is added.

The correct option is D 100J/kg⋅oCWe know that Q=msΔTSo, the specific heat, s=QmΔT=200010×2=100J/kgoC.Thus, the correct option will be D.

Calculate the specific heat of the material if material of 10 kilograms raises temperature $2^{o} C$ when 2000 joules of heat is added.

The correct option is D $100 J / k g \cdot^{o} C$
We know that $Q = m s Δ T$
So, the specific heat, $s = \frac{Q}{m Δ T} = \frac{2000}{10 \times 2} = 100 J / k g^{o} C$ .
Thus, the correct option will be D.
