Question

Calculate required heat energy to exchange 10gm of water from 30°c to40°c

Answer 1

Answer:

Convert 10 grams to pounds:

10⋅0.0022=0.022 pound

Convert 50 degrees C to Fahrenheit:

(50⋅95)+32=122 degrees Fahrenheit

Convert 40 degrees C to Fahrenheit:

(40⋅95)+32=104 degrees Fahrenheit

Calculate the change in temperature:

122−104=18 degrees Fahrenheit

Heat lost in British Thermal Units (BTU):

0.022⋅18=0.396 BTU

hope this is your answer

Use the formula Q= mcΘ where m is the mass of water in kg, c being the specific heat capacity of the object ( water in this case) approx. 4200 J/kg/ degree Celcius and Θ being the change in temperature in degree Celsius

So, convert 10g to Kg , which is .01 kg then find Θ ( 80–30) degree celcius. Now plug in the numbers.
