Answer : The heat created by the food is, 3971 J
Explanation :
Formula used:
where,
q = heat produced = ?
m = mass of water = 100 g
c = specific heat capacity of water =
= change in temperature =
Now put all the given values in the above formula, we get:
Therefore, the heat created by the food is, 3971 J
Answer : The correct option is,
Explanation :
The conversion used for the temperature from Fahrenheit to degree Celsius is:
where,
= temperature in Fahrenheit
= temperature in centigrade
The conversion used for the temperature from degree Celsius to Kelvin is:
where,
= temperature in Kelvin
= temperature in centigrade
As we are given the temperature in Fahrenheit is, -10
Now we have to determine the temperature in degree Celsius.
Now we have to determine the temperature in Kelvin.
Therefore, the temperature in degree Celsius and Kelvin are,
