Final answer:
The heat energy required to raise the temperature of 193 g of ethanol from 19°C to 35°C is calculated using the specific heat formula, resulting in 7590.08 J, which is not among the provided options.
Step-by-step explanation:
To calculate the heat energy required to raise the temperature of 193 g of ethanol from 19°C to 35°C, we can use the formula for heat energy (Q):
Q = m × c × ΔT
where:
- m is the mass of the ethanol (193 g),
- c is the specific heat of ethanol (2.46 J/g°C), and
- ΔT is the change in temperature (35°C - 19°C = 16°C).
Plugging the values into the equation:
Q = 193 g × 2.46 J/g°C × 16°C = 7590.08 J
Thus, the correct answer is not listed among the provided options. However, the closest option to the calculated value is A. 989.64 J, but one should note that this answer is incorrect based on the calculation. Please check the answer choices or the calculation for any errors.
