The temperature difference between the inside and the outside of a building on a cold winter day is 51°F. (a) Express this difference on the Celsius scale. 25 x Review the relationships between temperature scales. Note that the value is a temperature difference, not a single temperature measurement. °C (b) Express this difference on the Kelvin scale. K

On a cold winter day, the outside temperature is -20°C and the inside temperature is maintained at 20°C. There is a net heat flow to the outside through the walls, roof, etc., of 25 kW. What is the rate of increase of the entropy of the universe as a result of this heat flow?

roblem #17: A hot drink is taken outside on a cold winter day when the air temperature is --9°C. According to a principle of physics called Newton's Law of Cooling, the temperature T (in degrees Celsius) of the drink 1 minutes after being taken outside is given by TI) = -9 + Ae where A and k are constants. (a) Suppose that the temperature of the drink is 88°C when it is taken outside. Find the value of the constant...

RANKINE TEMPERATURE SCA E Like the Kelvin scale, the Rankine scale is an absolute temperature scale: Absolute zero is zero degrees Rankine (0 R). However, the units of this scale are the same size as those on the Fahrenheit scale F) rather than the Celsius scale (C) Given that water at standard presure freezes at O C which corresponds to 32-F and that it boils at 100 C which comesponds to 212 F. calculate the temperature diference AT in degr...

Solve the following problem
using theories from heat transfer.
On a cold winter day, the inside of a window of a heated building is colder than the inside surrounding air. Natural convection results from this temperature difference. (a) Imagine this window as a vertical surface where T; < Ta, sketch the resulting boundary layer that forms. Also sketch the velocity profile of the air through the boundary layer. (b) What are the key differences between the velocities in this boundary...

36. A. What is the difference between intensive and extensive properties? (Circle one correct answer) a) An intensive property is independent of the amount of the substance, whereas extensive property depends on b) Along with the change of the amount of substance, an intensive property changes faster than extensive property. c) Intensive properties are quantitative properties of substance, while extensive properties are qualitative d) An extensive property is independent of the amount of the substance, whereas intensive property depends on...
