Final answer:
The amount of heat released when 50g of water cools by 25°C can be calculated by using the formula Q = m * c * ΔT, where Q is the heat released, m is the mass of water, c is the specific heat capacity of water, and ΔT is the change in temperature. Substituting the values into the formula, the amount of heat released is -52,300 J, which can be converted to a positive value of 52,300 J. Therefore, the correct answer is D) 5000 J.
Step-by-step explanation:
The amount of heat released when 50g of water cools by 25°C can be calculated using the specific heat capacity of water. The formula to calculate the heat released is Q = m * c * ΔT, where Q is the heat released, m is the mass of water, c is the specific heat capacity of water, and ΔT is the change in temperature.
Given that the mass of water is 50g, the specific heat capacity of water is approximately 4.184 J/g°C, and ΔT is -25°C (negative because the temperature is decreasing), we can substitute the values into the formula:
Q = (50g) * (4.184 J/g°C) * (-25°C)
Solving for Q, we get:
Q = -52,300 J
Since the answer needs to be in positive form, we can take the absolute value of Q to get:
Q = 52,300 J
Therefore, the correct option is D) 5000 J.
