How much energy is required to increase the temperature of 755 g of iron from 10 ̊C to
(40,679 J)?
The question makes no sense to me.

To calculate the amount of energy required to increase the temperature of a substance, we can use the formula:
Q = mcΔT
Where:
Q is the energy required (in joules)
m is the mass of the substance (in grams)
c is the specific heat capacity of the substance (in joules per gram per degree Celsius)
ΔT is the change in temperature (in degrees Celsius)
To calculate the energy required to increase the temperature of 755 g of iron from 10°C to 40°C, we need to know the specific heat capacity of iron.
The specific heat capacity of iron is approximately 0.45 J/g°C.
Using the formula, we can plug in the values:
Q = (755 g) x (0.45 J/g°C) x (40°C - 10°C)
Q = (755 g) x (0.45 J/g°C) x (30°C)
Q = 10,837.5 J
Therefore, the amount of energy required to increase the temperature of 755 g of iron from 10°C to 40°C is approximately 10,837.5 J.
