Chapter 2: Thermal Physics (Pt.2) Flashcards
Define expansion.
The difference between the original size of the object and the size when it’s cooled or heated.
What happens when a solid is heated?
What happens when a liquid is heated?
What happens when a gas is heated?
What state of matter expands the most?
Gas
Why do gases expand the most?
Because they have very weak intermolecular forces between the particles compared to the other two states.
What is the specific heat capacity of a substance?
amount of energy required to raise the temperature of a substance to 1 degree.
Write the equation for specific heat capacity.
What is the melting point of a solid?
The temperature at which the solid has reached the such a high temperature that it begins to break down into a liquid.
What is the boiling point of a solid.
The temperature at which the liquid has reached such a high temperature that it begins to break down into a liquid.
What is the melting and boiling point of pure water.
melting point: 0 degrees
boiling point: 100 degrees.
How does evaporation occur?
How do you increase evaporation rate? Explain.
List the similarities and differences between evaporation and boiling
