Answer:
you can use the formula for heat capacity to calculate the change in temperature:
Q = m * c * ΔT
where Q is the heat added, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.
Plugging in the values given, we get:
10 J = 0.002 kg * 0.129 J/(g·°C) * ΔT
Simplifying and solving for ΔT, we get:
ΔT = 10 J / (0.002 kg * 0.129 J/(g·°C))
ΔT = 308.53 °C
Therefore, the temperature of the gold increases by approximately 308.53 °C when 10 J of heat is added to 2 g of gold.
