The significance of atoms in the formation of compounds is that atoms combine to form compounds. This process involves the bonding of atoms from different elements to create new substances with distinct properties.
What do these two changes have in common? Select all that apply.
• rust forming on a metal gate
• snails growing shells
(1 point)
• Both are chemical changes
• Both conserve mass
• Both are changes in state
• Both are only physical changes
• rust forming on a metal gate
• snails growing shells
(1 point)
• Both are chemical changes
• Both conserve mass
• Both are changes in state
• Both are only physical changes
The two changes have the following in common:
- Both are chemical changes (rust forming on a metal gate involves a chemical reaction, while snails growing shells involves biochemical processes).
- Both conserve mass (according to the law of conservation of mass, mass is conserved in both chemical and physical processes).
The other options do not apply:
- They are not changes in state.
- They are not only physical changes (as mentioned, rust formation is a chemical change).
Which of the following best describes the gravitational force on the Moon compared to Earth?
(1 point)
• The Moon has stronger gravity than Earth.
• The Moon has weaker gravity than Earth.
• The Moon has the same gravity as Earth.
• The gravity on the Moon depends on its distance from the Sun.
(1 point)
• The Moon has stronger gravity than Earth.
• The Moon has weaker gravity than Earth.
• The Moon has the same gravity as Earth.
• The gravity on the Moon depends on its distance from the Sun.
The statement that best describes the gravitational force on the Moon compared to Earth is: The Moon has weaker gravity than Earth.
The Moon's gravitational force is about 1/6th that of Earth's gravity.
What process transfers energy from the Sun's core to its surface? (1 point)
Convection
• Radiation
• Conduction
• Diffusion
Convection
• Radiation
• Conduction
• Diffusion
The process that transfers energy from the Sun's core to its surface is radiation.
In the core, nuclear fusion generates energy, which is then transferred outward through radiation and eventually reaches the surface. Convection occurs in the outer layers of the Sun, but the initial transfer of energy from the core primarily involves radiation.
Which two factors determine the strength of gravitational force between two objects? (1 point)
Mass and Color
• Distance and Shape
• Mass and Distance
• Color and Shape
Mass and Color
• Distance and Shape
• Mass and Distance
• Color and Shape
The two factors that determine the strength of gravitational force between two objects are Mass and Distance.
The gravitational force increases with greater mass and decreases with increasing distance between the objects.
