Slide 2 - Poll

describe changes of state: melting, boiling, evaporating, freezing and condensing,
describe the effects of temperature and pressure on the volume of a gas,
explain changes of state in terms of kinetic particle theory, including the interpretation of heating and cooling curves, and
describe trends and patterns in results, including identifying any anomalous results.

Interpretation

Sloped lines: temperature of the state of matter is increasing.
Horizontal lines: change of state (no change of temperature)
This is a HEATING CURVE.

Slide 43 - Slide

06 September 2023, Monday

Interpretation

Sloped lines: decrease in temperature
Horizontal lines: change of state (no change of temperature)
This is a COOLING CURVE.
