Hi! I have a question.
Unsatisfied with the Celsius and Fahrenheit temperature scales, you decide to create your own. On your temperature scale, the ice point is 77°M and the steam point is at 437°M, where "°M" stands for "my scale." What temperature on your scale corresponds to 68°F?
(A) 154°M, (B) 168°M, (C) 140°M, (D) 136°M, (E) 149°MMy answer below, is this correct?68°F = (E) 149°M
Soon after the Earth formed, heat released by the decay of radioactive elements raised the average internal temperature from 300 to 3000 K, at about which value it remains today. Assuming an average coefficient of volume expansion of 3.0 x 10-5 K -1 , by how much has the radius of the Earth increased since its formation? (Let r = 6400km be the present radius of the Earth.)
