To determine which substance would undergo a change of state from liquid to gas when the temperature is increased from -50°C to -20°C, we need to consider the boiling point of various substances.
If we are examining common substances, a good candidate is **ammonia (NH₃)**. The boiling point of ammonia is around -33.3°C. If the temperature is increased from -50°C to -20°C, it would first become liquid at the boiling point of ammonia, and then as the temperature continues to increase, it would vaporize into a gas.
Other substances that could fit this criterion would require similar boiling points below -50°C. In general, for a particular substance to transition from liquid to gas in that specified temperature range, its boiling point should be below -50°C but above -20°C.
In summary, ammonia is a suitable example of a substance that would change from liquid to gas when the temperature is increased within the specified range.
