The greater the surface area to volume ratio of an organism, the more heat is lost from their bodies. This is because heat can escape more readily if the ratio is larger. Although polar bears are massive, their relative surface area : volume proportion is small compared to animals that live in the desert, such as camels. Compare the short, stumpy legs of the bear, with the tall gangly limbs of camels.

Why is condensation heat loss?
Condensation leads to heat loss because the process of converting water vapor into liquid releases latent heat. As the water vapor cools down and condenses into liquid form, this released latent heat is transferred to the surroundings, resulting in a loss of heat from the system.
Is freezing ice heat gain or heat loss?
Freezing ice is a process that involves heat loss. When liquid water turns into ice, heat escapes from the water, causing it to lose energy and lower in temperature.
Is melting heat gain or heat loss?
Melting is a process that requires heat to change a solid substance into a liquid, so it is a heat gain process. Heat is absorbed to break the bonds between the molecules in the solid and allow them to move more freely as a liquid.
Is condensation a energy loss or gain?
Condensation is typically considered an energy loss because it releases energy as heat when water vapor changes to liquid water. This energy is known as latent heat of condensation.
Why does a bulky body tend to conserve more heat than a slender one?
A bulky body has a smaller surface area-to-volume ratio, which means there is less surface area from which heat can escape compared to the volume that retains heat, leading to better heat conservation. In contrast, a slender body has a larger surface area relative to its volume, which results in more heat loss to the environment.
What factors affect the loss of heat from a liquid?
true
Does the diameter surface area and circumference affect the heat loss?
yes heat loss is affected by diameter, circumference and surface area. Heat loss depends on the surface area : volume ratio.......the larger this is the more heat is lost if a cylinder having the same volume but a different surface area...(therefre radius and circumference is different)........the cylinder having the larger surface area will loose heat fastest
How does the thickness of loft insulation affect heat loss?
the thicker the insulation is then there will be less heat loss. The material also affects heat loss
Why is condensation heat loss?
Condensation leads to heat loss because the process of converting water vapor into liquid releases latent heat. As the water vapor cools down and condenses into liquid form, this released latent heat is transferred to the surroundings, resulting in a loss of heat from the system.
Which changes occur during evaporation?
During evaporation, liquid water gains enough energy to break free from the surface of the liquid and turn into water vapor. This process involves the transfer of heat energy from the surroundings to the liquid. As a result, the liquid slowly decreases in volume and the temperature of the remaining liquid may decrease due to the loss of heat energy.
Does temperature affect heat loss in water?
Yes, it does.
How do you use steam tables?
The steam tables have 16 columns as follows: pressure (absolute), temperature, specific volume of vapor, specific volume of liquid, heat of the liquid, heat of vaporization, total heat of the vapor, entropy of the liquid, entropy of vaporization, entropy of the vapor, internal heat of the liquid, internal heat of vaporization, and internal heat of the vapor (occasionally the external heat of the liquid, vaporization and vapor are included) If the temperature and pressure of steam are known then cross referencing the heat or the volume of a known quantity of the steam can be done. the heat content(enthalpy) of the liquid or vapor can be extrapolated from the chart, as can the entropy and internal energy. The enthalpy less the internal energy = the external energy (or the actual energy required to expand the liquid to a vapor) By determining the starting heat content of steam and final or exhaust heat content of steam the efficiency of a steam engine can be determined. Along with these calculations are the determinations of heat losses, steam quality, loss to entropy,...etc. all calculated using various instruments and the steam tables.
How colours affect heat loss?
blue blue blue
Is there loss of heat during change of state of matter from liquid to gas?
Yes there must be achange;but heat is required to change liquid state into gaseous state.
Does heat affect starch?
Yes, heat can affect starch. When starch is exposed to heat, it undergoes gelatinization, where the starch granules absorb water, swell, and eventually burst, resulting in thickening of a liquid. Continued heating can break down the starch molecules further, leading to a loss of thickening properties.
Is freezing ice heat gain or heat loss?
Freezing ice is a process that involves heat loss. When liquid water turns into ice, heat escapes from the water, causing it to lose energy and lower in temperature.
What are the pros and cons on liquid solar blankets?
Liquid solar blankets can help reduce water evaporation and heat loss in pools, which can lead to energy savings. However, they need to be reapplied frequently and may not be as effective as physical covers in retaining heat. Additionally, some liquid solar blankets can affect water chemistry and filtration systems.
