To calculate the heat needed to raise the temperature of a substance, you can use the formula:

Q = mcΔT

Where: Q = heat (in joules) m = mass of the substance (in grams) c = specific heat capacity of the substance (in J/g°C) ΔT = change in temperature (in °C)

For iron, the specific heat capacity is approximately 0.45 J/g°C.

Given: m = 26 g ΔT = (45°C - 25°C) = 20°C

Plug the values into the formula:

Q = (26 g) * (0.45 J/g°C) * (20°C) Q = 234 J

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
