Question

a sample of water is heated from 25°C to 35°C. How much is the rise in temperature on Fahrenheit and Kelvin scale?

Answer 1

if any one is unsatisfied. comment please

Answer 2

Answer: Raise in temperature in Kelvins = 283.15 Kelvins

Raise in temperature in degree Fahrenheit = $18^oF$

Solution:

Raise in temperature in Kelvins:

$T(K)= 273K+T(^oC)$

Initial temperature: $25^oC=298K$

Final temperature: $35^oC=308K$

Raise in temperature: $308-298=10K$

Raise in temperature in degree Fahrenheit :

$1^oC=(33.8^oF-32)\times \frac{5}{9}$

Initial temperature: $25^oC=77^oF$

Final temperature: $35^oC=95^oF$

Raise in temperature in degree Fahrenheit = $(95-77)^oF=18^oF$
