A40 wt% pb–60 wt% mg alloy is heated to a temperature within the α + liquid-phase region. if the mass fraction of each phase is 0.5, then estimate:

(a) the temperature of the alloy
(b) the compositions of the two phases in weight percent
(c) the compositions of the two phases in atom percent

it was a fall down when it happens

explanation:

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
