2 . You know that the regular temperature for the healthy person is about 98. 6 F degrees. Express this temperatures in certifications Celsius.

F sama dengan 1 . EIGHT DEGREE CENTIGRADE + thirty-two F sama dengan 1 . EIGHT DEGREE CENTIGRADE + 32

Farreneheit ” thirty-two = 1 . 8C

(F-32)/1. eight = C

C = (98. 6 ” 32)/1. almost 8

= 66. 6/1. 8

= 37degC

4. Answer the following questions:

A. Illustrate and make clear the meaning of the graph.

The chart shows how after the period the water begins to slowly decrease in temperature until it is at a well balanced temperature. M. What is happening towards the average kinetic energy with the molecules during the five minutes when the temperature from the water had been recorded? Explain your answer. Well, after each 31 second period the temperatures begin to become equal, following the five minutes are up the two waters just about the same actual temperature.

your five. A material rod is 25. 000cm long at 25. zero degrees C. When warmed to 102. 0 certifications Celsius, it truly is 25. 054 cm long. What is the coefficient of linear expansion for this metallic? ΔL=aL€Î”T

a = ΔL/(L€Î”T)

a = (25. 054 cm ” 25. 000cm)/[25. 000cm(102. 0C ” twenty-five. 0C)]

a = 2 . 805×10-^5/C
