Yes, Rigel has a much higher luminosity than the Sun, being around 120,000 times more luminous. However, it also has a lower surface temperature than the Sun, with a surface temperature of around 11,000 Kelvin compared to the Sun's temperature of approximately 5,500 Kelvin.
No, the luminosity of a star depends on both its surface temperature and its mass. Increasing the mass of the Sun while keeping its surface temperature the same would actually cause it to be more luminous due to increased gravitational energy being converted into light.
Yes, generally the hottest main sequence stars are also the most massive. This is because more massive stars have higher core temperatures and pressures, resulting in hotter surface temperatures. Therefore, there is a direct correlation between a star's mass and its surface temperature on the main sequence.
A red giant can become brighter if its core temperature increases due to increased fusion reactions. Even though the surface temperature decreases, the overall luminosity of the star can increase if the core fusion rate intensifies, producing more energy.

Compared to less massive particles at the same temperature, more massive particles have lower average speeds due to their higher inertia. This results in more frequent collisions with other particles, leading to increased pressure in a gas.
When blood vessels in the skin dilate, more blood flows to the skin's surface, allowing heat to escape from the body more easily. This process helps to lower the temperature of the skin surface.
To lower the temperature at which evaporation takes place, you can decrease the pressure or increase the surface area of the liquid. This allows the liquid molecules to escape into the air more easily, leading to evaporation at a lower temperature.

Surface tension of water decreases as temperature increases. At lower temperatures, water molecules are more closely packed, leading to stronger intermolecular forces and higher surface tension. As temperature rises, water molecules gain kinetic energy and move more freely, causing weaker intermolecuar attractions and lower surface tension.
The ocean is larger than a lake. Therefore, being larger it can absorb more heat. That is why a lower temperature is needed to freeze it.

Stars with a surface temperature of around 3000 degrees Celsius appear red in color. This is because their lower temperature causes them to emit more red and infrared light compared to higher temperature stars.
If you increase the albedo, more solar radiation will be reflected back into space and so the temperature will be lowered.
