Question:
This graph in the figure?(Figure 1)?shows how the temperature of an initially solid sample changes as time goes by when it is placed above a flame that delivers a constant heating power (that is, a fixed amount of energy input in the form of heat each second). The process occurs in five distinct steps:
- Increase the temperature of the solid until it reaches its melting temperature.
- Melt the solid to form a liquid, maintaining a constant temperature.
- Increase the temperature of the liquid until it reaches its boiling temperature.
- Boil away all the liquid to form a gas, maintaining a constant temperature.
- Increase the temperature of the gas (this assumes that the gaseous sample is confined).
Part A
Use the graph to rank the sizes of the following:
- specific heat of the solid,
- specific heat of the liquid,
- specific heat of the gas,
Keep in mind that energy is being delivered to the system in the form of heat at a constant rate by the flame.
Rank from largest to smallest specific heat. To rank items as equivalent, overlap them.
