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:
