Question 2

)  In the calculation set-up below to determine how much heat is needed to convert 50 g of ice at ?20 °C to steam at 300 °C, which constant does C represent?
(A) (50 g) (20 °C)  + (heat of fusion) (50 g)  + (B) (50 g) (100 °C)  + (heat of vap.) (50 g)  + (C) (50 g) (200 °C)  = total heat

Accepted Answer

A)   specific heat of ice
B)   specific heat of water
C)   specific heat of steam
D)   heat capacity of water

Question 3

Which statement about the boiling point of water is incorrect?

Accepted Answer

A)   The boiling point is greater than 100 °C in a pressure cooker.
B)   The boiling point is less than 100 °C for locations at low elevations.
C)   At sea level and at a pressure of 760 mm Hg, the boiling point is 100 °C.
D)   In a pressure cooker, shorter cooking times are required due to the change in boiling point.
