During a heating process, the temperature of an object rises by 7°C. This temperature rise is equivalent to a temperature rise of:

A. 10 degrees F
B. 42 degrees F
C. 12 K
D. 18 K
E. 283 K

Answer :

The temperature rises by 7⁰ C is equivalent to a temperature of 283 K (option e).

We can convert the temperature rise in Celsius to other temperature units using the following formulas:

  • To convert Celsius to Fahrenheit: F = (C × 9/5) + 32
  • To convert Celsius to Kelvin: K = C + 273.15

Using these formulas, we can find the equivalent temperature rise in each of the given units:

a. To convert 7°C to Fahrenheit: F = (7 × 9/5) + 32 = 44.6°F

Therefore, the temperature rise is not equivalent to 10°F.

b. To convert 7°C to Fahrenheit: F = (7 × 9/5) + 32 = 44.6°F

Therefore, the temperature rise is not equivalent to 42°F.

c. To convert 7°C to Kelvin: K = 7 + 273.15 = 280.15 K

Therefore, the temperature rise is not equivalent to 12 K.

d. To convert 7°C to Kelvin: K = 7 + 273.15 = 280.15 K

Therefore, the temperature rise is equivalent to 280.15 - 273.15 = 7 K.

e. To convert 7°C to Kelvin: K = 7 + 273.15 = 280.15 K

Therefore, the temperature rise is equivalent to 280.15 K - 273.15 K = 7 K.

Therefore, the correct answer is either d. 18 K or e. 283 K. However, since 18 K is not among the options, the answer must be e. 283 K.
