A sample of water was heated from 250C to 350C. How much was the rise in temperature on Kelvin scale?
Answers
Explanation:
We know that K =C + 273
thus 25oC converted into Kelvin scale will give, K = 25+273
= 298K
35oC converted into Kelvin scale will give , K = 35 +273
= 308 K
So,
i) Initial temperature on Kelvin scale will be = 298K
Final temperature on Kelvin scale will be = 308K
ii)Rise in temperature on the Celcius scale = [35-25]oC
= 10oC
iii)Rise in temperature of water on the Kelvin scale = [308-298]K
= 10 K
iv)The temperature in degree Fahrenheit (oF) is related to the temperature in oC by the relation
T[oF] = T [oC] × 95 +32
Initial temperature in oF = 25 × 95 + 32
= 77oF
Final temperature in oF = 35 × 95 + 32
= 95oF
Therefore rise in temperature in oF = [95-77]oF
= 18oF
