What else can I help you with?
What happens when an object at a high temperature touches an object at lower temperature?
Heat is conducted form the high temperature body to the low temperature body until their temperatures are the same.
Can heat transfer from one object to with the same temperature?
This is not possible. Heat always move from a body of high temperature to a body of low temperature.
What is the major properties of water that make it so vital to the proper functioning of the body with high heat?
At high temperatures water regulates the bodies temperature, the bodies temp needs to be about 36.7, but as it functions the body generates heat, If the surroundings are hot the body can't lose the heat it generates to the air, so water is excreted as sweat to lower the body temperture
What is the specific heat of a mammalian body and how does it affect the body's ability to regulate temperature?
The specific heat of a mammalian body is approximately 3.5 J/gC. This means that it takes a relatively large amount of energy to change the temperature of the body. This high specific heat helps the body regulate its temperature by absorbing and releasing heat slowly, which helps maintain a stable internal temperature despite external temperature changes.
Why do humans perspire in high temperature?
since our bodies have a mechanism for losing heat when temperature of body rises . when sweat comes out the ,water vaporizes utilizing latent heat of vaporization from our body this heat gets deducted from our body's temperature. hence to keep our inside cool and maintain a temperature of 36 degree celsius we have to perspire
Why does heat unevenly?
High temperature High temperature
Why heat gained and heat loss?
Since heat flows from high temperature region to low temperature region so when a hotter body comes in contect with colder body then hotter body loses heat to colder body until both have same temperature.
What direction does heat trasfer?
Heat transfer occurs from areas of higher temperature to areas of lower temperature in the direction of decreasing thermal energy. Heat transfer can occur through conduction, convection, or radiation depending on the medium through which it is transferring.
What is the ability of water to maintain a relatively constant temperature and then prevent rapid changes in body temperature due to?
Water has a high specific heat capacity, meaning it can absorb and release large amounts of heat with minimal temperature change. This property helps regulate body temperature by buffering against rapid temperature fluctuations in the environment. Additionally, water's high thermal conductivity allows for efficient heat transfer, aiding in the maintenance of a stable internal body temperature.
High air temperature reduces body's ability to lose heat by?
Increasing the gradient between body temperature and the surrounding environment, leading to less efficient heat transfer through convection and radiation.
How does the hydrosphere moderates temperature and transfers heat?
The hydrosphere moderates temperature through its high heat capacity, which means it can absorb and release large amounts of heat before changing temperature significantly. Water bodies like oceans and lakes transfer heat through processes like conduction, convection, and radiation, helping to regulate Earth's climate and distribute heat around the planet.
How water is a good regulator of body temperature?
Water has an amazingly high specific heat compared to most substances so for example: adding or removing 1 Joule of energy from 1000 cm3 of water will change its temperature much less than it would change 1000 cm3 of most other substances.
