If you were going to heat 10g of water, which would require more heat? a. raising he temperature 10*F b. raising the temperature 10*C c. raising the temperature 10 K d. answers b and c are the same (I think the answer is a, since c=k are equal and f=9/5c)
A Celcius degree is almost 2 degrees F. B and C are the same, and require more heat. Remember 100C is 180F in change.
so the answer is d?
yes.
To determine which option would require more heat to raise the temperature of 10g of water, let's analyze the provided choices:
a. Raising the temperature 10*F
b. Raising the temperature 10*C
c. Raising the temperature 10 K
d. Answers b and c are the same
To find the correct answer, we need to understand the relationship between Fahrenheit (F), Celsius (C), and Kelvin (K) scales.
The Fahrenheit and Celsius scales are related by the equation: F = (9/5)C + 32.
Converting between Celsius and Kelvin, we use the equation:
K = C + 273.15.
Now let's compare options b and c:
b. Raising the temperature 10*C: This means increasing the temperature by 10 degrees Celsius.
c. Raising the temperature 10 K: This means increasing the temperature by 10 Kelvin.
Since the Kelvin scale starts at absolute zero (0 K) and does not have negative values, it is always higher than the Celsius scale. This means that raising the temperature by 10 K will always require more heat compared to raising the temperature by the same amount in degrees Celsius.
Therefore, the correct answer is d. Answers b and c are the same.
To clarify, when raising the temperature by 10*C or 10 K, the amount of heat energy required is the same because the difference between them is constant (273.15). Meanwhile, increasing the temperature by 10*F would require less heat energy in comparison.
