Final answer:
The increase in thermal energy when the temperature of 10 g of water is raised from 15°C to 35°C is approximately 836 J.
Step-by-step explanation:
The specific heat of water is 4.18 J/g°C. To find the increase in thermal energy, we can use the formula: q = m * c * ΔT, where q is the thermal energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.
In this case, the mass of water is 10 g, the specific heat capacity is 4.18 J/g°C, and the change in temperature is 35°C - 15°C = 20°C.
Therefore, the increase in thermal energy is approximately 10 g * 4.18 J/g°C * 20°C = 836 J.
