Review for Flashcard 4, Semester 1

Front

What is the method used to measure the volume of an irregularly shaped object?

Back

The volume of an irregularly shaped object can be measured by displacement, which involves submerging the object in a fluid and measuring the volume of fluid displaced.

Front

What is the significance of the estimated digit in a measurement?

Back

The estimated digit in a measurement indicates the precision of the measurement. It is the last digit that is uncertain and is based on the measurement tool's resolution.

Front

How is density defined in terms of mass and volume?

Back

Density is defined as mass per unit volume, typically expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

What happens to the boiling point of a liquid when the amount of the sample is increased?

Back

The boiling point of a liquid remains constant regardless of the amount of the sample, as long as the pressure remains the same.

Front

What is an extensive property in thermodynamics?

Back

An extensive property is a property that depends on the amount of matter in a sample, such as mass, volume, and total energy.

Front

What is the boiling point of water at standard atmospheric pressure?

Back

The boiling point of water at standard atmospheric pressure (1 atm) is 100 degrees Celsius.

Front

What is the relationship between mass and weight?

Back

Mass is a measure of the amount of matter in an object, while weight is the force exerted by gravity on that mass. Weight can vary with the strength of the gravitational field.

Front

How do you calculate the density of an object?

Back

Density can be calculated using the formula: Density = Mass / Volume.

Front

What is the difference between intensive and extensive properties?

Back

Intensive properties do not depend on the amount of substance present (e.g., density, boiling point), while extensive properties do depend on the amount of substance (e.g., mass, volume).

Front

What is the principle of buoyancy related to displacement?

Back

The principle of buoyancy states that an object submerged in a fluid experiences an upward force equal to the weight of the fluid displaced by the object.
