A thermogram is a representation of infrared electromagnetic waves better known as heat waves. So the correct answer is infrared electromagnetic waves or infrared waves.
Explanation:
The thermogram is associated with infrared camera creates a picture by changing effulgent heat into a symbol which will be displayed on a monitor (and later printed). The infrared energy emitted from the associated object is directly proportional to its temperature. Thus it can be used for temperatures that are accurately measured by the infrared camera.
Answer : Heat required, Q = 5000 cal
Explanation :
It is given that,
Specific heat of water, c = 1 calorie/gram °C
Mass of water, m = 500 grams
Change in temperature,
We have to found the amount of heat required. Mathematically, it can be written as :
Q = 5000 cal
So, the correct option is (B) " 5000 cal ".
Hence, this is the required solution.
5000 calories Helps :)
