When the temperature of water increases from room temperature to 90ºc the process of heating the water question 9 options:
a. adiabatic
b. exothermic
c. isothermic
d. endothermic
e. all of the above

Answer : The correct option is, (D) Endothermic

Explanation :

Adiabatic : It is a process in which a heat is constant. That means no heat is lost or gained by the system.

Isothermic : It is a process in which a temperature is constant.

Exothermic : It is a process in which heat released from system to surrounding. In this process, surrounding temperature increases and system temperature decreases.

Endothermic : It is a process in which heat required from the surrounding. In this process, surrounding temperature decreases and system temperature increases.

When the temperature of water increases from room temperature to 90ºC the process of heating the water is endothermic.

Hence, the correct option is, (D) Endothermic

do you have a formula possibly

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
