To find the specific heat (
) of the metal, we can use the formula provided:
where:-
is the amount of heat absorbed (4256.4 Joules),-
is the mass of the sample (150 grams),-
is the change in temperature.First, calculate the change in temperature (
):
Now, substitute the values into the formula:
Calculate the denominator:
Now, divide the numerator by the denominator:
Therefore, the specific heat (
) of the metal is approximately:
The correct answer is:
