Final answer:
The amount of thermal energy required to increase the temperature of 25.0 g of silver from 50.0 °C to 80.0 °C is 173.25 J.
Step-by-step explanation:
To calculate the amount of thermal energy required to increase the temperature of 25.0 g of silver from 50.0 °C to 80.0 °C, we can use the equation:
Q = m × c × ΔT
- Q is the thermal energy
- m is the mass of the silver (25.0 g)
- c is the specific heat of silver (0.233 J/g.°C)
- ΔT is the change in temperature (80.0 °C - 50.0 °C = 30.0 °C)
Substituting the values into the equation, we get:
Q = (25.0 g) × (0.233 J/g.°C) × (30.0 °C) = 173.25 J
Therefore, the amount of thermal energy required is 173.25 J.
