How much heat would be released by 1.3 kg of water if it's temperature went from 295 k to 274 k
1 answer:
Answer: The energy released will be 114.223 kJ.
Explanation:
To calculate the amount of heat released, we use the formula:
Q = heat gained or released
m = mass of the substance = 1.3kg = 1300 g (Conversion factor: 1kg = 1000g)
c = heat capacity of water = 4.184 J/g K
Putting values in above equation, we get:
Q = -114223 Joules = -114.223 kJ (Conversion Factor: 1kJ = 1000J)
Negative sign implies heat released.
Hence, heat released by 1.3 kg of water is 114.223kJ.

A cell is the structural and fundamental unit of life. The study of cells from its basic structure to the functions of every cell organelle is called Cell Biology. Robert Hooke was the first Biologist who discovered cells
two types of cell
1) Prokaryotes
2) Eukaryotes
Characteristics of Cells
1) Cells provide structure and support to the body of an organism.
2) The cell interior is organised into different individual organelles surrounded by a separate membrane.
3) The nucleus (major organelle) holds genetic information necessary for reproduction and cell growth
