6 SCI 1.2 Measuring Matter

What is the amount of matter in an object called?

• Volume

• Weight

• Density

• Mass

Answer explanation

The amount of matter in an object is called its mass. Mass is a measure of the quantity of matter, while volume refers to the space an object occupies, weight is the force due to gravity, and density is mass per unit volume.

What term describes the amount of space that matter occupies?

• Mass

• Weight

• Volume

• Density

Answer explanation

The term that describes the amount of space that matter occupies is 'Volume'. Mass refers to the amount of matter, weight is the force of gravity on an object, and density is mass per unit volume.

What is the force of gravity on an object known as?

• Mass

• Weight

• Volume

• Density

Answer explanation

The force of gravity acting on an object is referred to as its weight. Weight is the product of mass and the acceleration due to gravity, distinguishing it from mass, volume, and density.

What is the measure of mass in a given volume called?

• Mass

• Weight

• Volume

• Density

Answer explanation

The measure of mass in a given volume is called density. It quantifies how much mass is contained in a specific volume, distinguishing it from weight, which is the force due to gravity, and volume, which measures space.

What unit is mass measured in?

• Kilograms

• Pounds

• Grams

• Ounces

Answer explanation

Mass is commonly measured in grams, which is a standard unit in the metric system. While kilograms and pounds are also units of mass, grams is the correct answer in this context.

Which of the following statements is true about mass?

• Mass is affected by gravity

• Mass is the same as weight

• Mass is not affected by gravity

• Mass is measured in liters

Answer explanation

Mass is a measure of the amount of matter in an object and is not influenced by gravity. Unlike weight, which varies with gravitational force, mass remains constant regardless of location.

What instrument is often used to measure mass?

• Thermometer

• Ruler

• Balance scale

• Stopwatch

Answer explanation

A balance scale is specifically designed to measure mass by comparing an object to known weights, making it the correct choice. A thermometer measures temperature, a ruler measures length, and a stopwatch measures time.

How does weight change?

• It remains constant

• It changes depending on the amount of gravity

• It changes depending on the temperature

• It changes depending on the volume

Answer explanation

Weight changes depending on the amount of gravity acting on an object. On different planets or altitudes, gravity varies, thus affecting weight, while mass remains constant.

How is weight measured?

• By a thermometer

• By a ruler

• By a scale

• By a stopwatch

Answer explanation

Weight is measured by a scale, which quantifies the force of gravity on an object. A thermometer measures temperature, a ruler measures length, and a stopwatch measures time, making them unsuitable for measuring weight.

What happens to weight when gravity increases?

• Weight decreases

• Weight remains the same

• Weight increases

• Weight becomes zero

Answer explanation

When gravity increases, the force acting on an object also increases, which results in a higher weight. Therefore, weight increases with an increase in gravity.
