Answer:
The ball will lose heat at the rate of 0.072 J/min.
Explanation:
According to the Newton's cooling law, the rate of cooling R is given by the formula.
R=-k(T-To)
where k is a constant, T is the temperature of the object and To is the temperature of the surrounding.
Initially, R=0.15 J/min, To=700 K and T=950 K.
So 0.15=-k(950-700)
k=-0.15/250 J/K min.
Finally, To=700 K and T=820 K
R=-(-0.15/250)(820-700)
R= 0.072 J/min

The third law of thermodynamics is concerned about the entropy of the system. This states that the entropy of the perfect crystal is zero only when the temperature of the crystal is equal to the absolute zero which is equal to zero kelvin.
Answer:
Atelectasis
Explanation:
Atelectasis is defined as the partial or completely collapsion of lungs, it is caused because of the collapse of tiny sacs of lungs or with the possibility, that these space is filled by the alveolar fluid.
Atelectasis is the condition in which the surface area of the alveolar is collapse, this can be caused due to the absence of surfactants. This condition will result in decrease or reduction of gas exchange.
