Heat capacity temperature of blood

In summary, blood carries excess energy from the interior of the body to the surface, where it is dispersed. During exercise, 0.8 kg of blood flows to the surface and releases 1300 J of energy. The temperature of the blood arriving at the surface is 37.0 °C. Using the specific heat capacity of water (cwater = 4186 J kg−1.°C−1), the temperature of the blood leaving the surface and returning to the interior can be determined.

Homework Statement



Blood can carry excess energy from the interior to the surface of the body, where the energy is dispersed in a number of ways. While a person is exercising, 0.8 kg of blood flows to the surface of the body and releases 1300 J of energy. The blood arriving at the surface has the temperature of the body interior, 37.0 °C.
(Note: cwater = 4186 J kg−1.°C−1)
Assuming that blood has the same specific heat capacity as water, determine the temperature of the blood that leaves the surface and returns to the interior.

1. What is heat capacity temperature of blood?

Heat capacity temperature of blood is the measurement of how much heat energy is required to raise the temperature of a certain amount of blood by 1 degree Celsius. It is a property that describes the ability of blood to absorb and retain heat.

2. Why is heat capacity temperature of blood important?

The heat capacity temperature of blood is important because it helps regulate our body temperature. Blood carries heat throughout the body, and its ability to absorb and release heat helps maintain a stable internal temperature, which is crucial for our overall health and well-being.

3. How does the heat capacity temperature of blood differ from water?

The heat capacity temperature of blood is slightly higher than water, meaning it takes more heat energy to raise the temperature of blood by 1 degree Celsius compared to water. This is because blood has additional components, such as proteins and cells, that contribute to its heat capacity.

4. Does the heat capacity temperature of blood change?

Yes, the heat capacity temperature of blood can change depending on factors such as age, health, and physical activity. For example, newborns have a higher heat capacity temperature compared to adults, and individuals with certain medical conditions may have a lower heat capacity temperature.

5. How is the heat capacity temperature of blood measured?

The heat capacity temperature of blood is typically measured in a laboratory setting using a device called a calorimeter. This instrument measures the amount of heat energy required to raise the temperature of a known amount of blood by a certain amount. The results are then used to calculate the heat capacity temperature of blood.
