Explanation:
a) The specific heat capacity means the amount of heat needed by a unit mass of a material to increase its temperature in one unit.
b) Let suppose that heat transfer rates between liquids and surroundings are stable. The quantity of the heat released is determined by the following expression:
(1)
Where:
- Mass of the liquid, in kilograms.
- Specific heat capacity, in joules per kilogram-degree Celsius.
- Initial temperature of the sample, in degrees Celsius.
- Freezing point, in degrees Celsius.

Answer:
40
Explanation:
If it is a flat mirror, the reflection and incidence are the same -- 40 degrees.
If it is anything else, more information is needed.
Answer:
Diffusion is the movement of a molecule from an area where the molecule is in high concentration to an area where the molecule is in low concentration. Facilitated diffusion is the movement of a molecule from an area of high concentration to an area where the molecule is in low concentration. Osmosis is the diffusion (high to low concentration) of water through a semi-permeable membrane. Water moves from an area of high water molecule concentration (and lower solute concentration) to an area of low concentration (and higher solute concentration.

Answer:
The skin releases sweat
Explanation:
The body temperature is necessary to maintain homeostasis. Skin controls body temperature by sweating when it is too heated.
