Answer:
Step-by-step explanation:
To calculate the amount of heat required to raise the temperature of 586 g of copper from 22.3°C to 49.8°C, we can use the following formula:
Q = m x c x ΔT
where Q is the amount of heat, m is the mass of the substance, c is the specific heat, and ΔT is the change in temperature.
Plugging in the given values, we get:
Q = (586 g) x (0.377 J/g °C) x (49.8°C - 22.3°C)
Q = 13191.168 J
Therefore, the amount of heat that needs to be added to 586 g of copper to raise its temperature from 22.3°C to 49.8°C is 13191.168 J, which is equivalent to 1.32 x 10^4 J when expressed in scientific notation.
