Answer:
Silver.
Explanation:
To obtain the right answer to question, let us calculate the change in temperature for each substance assuming they all have the same mass as 100g.
This is illustrated below:
1. For Siver:
Mass (M) = 100g
Specific heat capacity (C) = 0.239J/g°C
Heat (Q) = 100 kJ = 100000J
Change in temperature (ΔT)
Q = MCΔT
ΔT = Q/MC
ΔT = 100000/(100 x 0.239)
ΔT = 4184°C
2. For Aluminium:
Mass (M) = 100g
Specific heat capacity (C) = 0.921J/g°C
Heat (Q) = 100 kJ = 100000J
Change in temperature (ΔT)
Q = MCΔT
ΔT = Q/MC
ΔT = 100000/(100 x 0.921)
ΔT = 1086°C
3. For Lithium:
Mass (M) = 100g
Specific heat capacity (C) = 3.56J/g°C
Heat (Q) = 100 kJ = 100000J
Change in temperature (ΔT)
Q = MCΔT
ΔT = Q/MC
ΔT = 100000/(100 x 3.56 )
ΔT = 281°C
4. For water:
Mass (M) = 100g
Specific heat capacity (C) = 4.184J/g°C
Heat (Q) = 100 kJ = 100000J
Change in temperature (ΔT)
Q = MCΔT
ΔT = Q/MC
ΔT = 100000/(100 x 4.184)
ΔT = 239°C
Summary
Temperature change of each substance is given below
1. Silver => 4184°C
2. Aluminum => 1086°C
3. Lithium => 281°C
4. Water => 239°C
From the calculations made above, Silver has the highest rise in temperature.
