Answer:
(a) W
(b) X
(c) Y
Explanation:
Let's consider the following table with melting and boiling points for 4 substances.
Substance Melting Point (°C) Boiling Point (°C)
W -7 60
X 660 2500
Y 180 1330
Z 115 445
Let's consider that:
- Below the melting point, a substance is solid.
- Between the melting and the boiling point, a substance is liquid.
- Above the boiling point, a substance is gas.
(a) Which substance is a gas at 100°C?
At 100 °C, W is above the boiling point
(b) Which substance is a liquid for the largest range of temperature?
The largest difference between the melting point and the boiling point is that of X: 2500 - 660 = 1840.
(c) Which substance is liquid at 1000 °C and a gas at 2000°C?
Y is between the melting and the boiling point at 1000 °C and above the boiling point at 2000 °C.
