<span>In 2013, MIT biophysicist proposed a new theory that atoms can restructure themselves to dissipate more energy under the right conditions (external energy and heat)-atoms, therefore, can take on qualities we associate with life. According to his theory, this may be the basis for lifeform as we know it.</span>
1550J
Explanation:
Given parameters:
Heat of fusion = 155J/g
Mass of sample = 10g
Unknown:
Quantity of heat removed to freeze the substance =?
Solution:
This is a phase change problem and we apply the formula for the specific heat of fusion to solve the problem:
Q = mL
m is the mass of the substance
L is the specific heat of fusion of the substance.
We then plug the parameters into the equation:
Q = 155J/g x 10g = 1550J
