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 0.3 kg of blood flows to the body's surface and releases 2000 j of energy. the blood arriving at the surface has a temperature of the body's interior, 37.0 oc. assuming that the blood has the same specific heat capacity as water, determine the temperature of the blood that leaves the surface and returns to the interior.

The temperature of the blood that leaves the surface and returns to the interior is: 35.41°C

Explanation:

We need to apply the equation of specific heat (), where Q is heat, m is mass, C is the specific heat capacity constant of the material and T is the temperature. The excersice said we can assume that the blood has the same specific heat capacity as water, so , knowing this and remembering that the energy is released on the surface(-Q), we can replace the values given and get: that is the temperature of the blood that leaves the surface.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

its a 5.5 n

glad that
