What occurs when light waves travling through the air reflect off small particles?
When light waves traveling through the air reflect off small particles, it results in a phenomenon known as scattering. The scattering of light causes the particles to become visible as they redirect light in various directions, creating effects like the blue color of the sky or the white appearance of clouds.

What is the transfer of energy by movement of particles?
Conduction is the transfer of energy by movement of particles in a material. This occurs when vibrating particles transfer energy to neighboring particles through direct contact. Heat is a common form of energy transferred through conduction.
How would heat transfer occur in the following substances or objects?
Conduction: Heat transfer in metals occurs through conduction, where heat moves through the material by vibrating particles passing on energy to neighboring particles. Convection: Heat transfer in fluids like water or air occurs through convection, where heated particles rise and cooler particles sink, creating a circular motion that transfers heat. Radiation: Heat transfer in a vacuum, like from the sun to the earth, occurs through radiation, where electromagnetic waves carry heat energy without the need for a medium to travel through.
What are the two ways that heat can be transferred?
Heat can be transferred through conduction, which occurs when heat moves through a solid material, and through convection, which happens in fluids like air and water when heated particles rise and cooler particles sink.
Does radiation involve heat passing through particles?
Heat doesn't pass through particles. On an atomic or sub-atomic level, heat is the speed with which the particles are either vibrating or moving. Some kinds of radiation are related to the temperature of the particles that emit the radiation, other kinds are not.
Is it true or false that heat travels through solids by conduction?
True. Heat travels through solids by conduction, which is the transfer of heat through direct contact between particles within the material. This process occurs as the faster-moving particles transfer energy to neighboring slower-moving particles.

How can water resistance be explained by particles?
Water resistance occurs when particles in the water disrupt the flow of objects moving through it. These particles can create drag and friction, making it harder for objects to move smoothly through the water. The more particles present in the water, the greater the resistance an object will experience.
Is it true or false that heat travels through solids by conduction?
True. Heat travels through solids by conduction, which is the transfer of heat through direct contact between particles within the material. This process occurs as the faster-moving particles transfer energy to neighboring slower-moving particles.
What is the natural spreading particles through liquids and gases called?
Diffusion
What do heat travel through solids by?
Heat travels through solids by a process called conduction, where energy is transferred between neighboring particles through direct contact. This transfer of thermal energy occurs as higher energy particles collide with lower energy particles, transferring heat along the material.
Which type of heat transfer does not involve particles?
Radiant heat does not require particles. It involves light in the infrared range.
What heat transfer is where heat energy is transferred by particles to neighbouring particles?
Conduction is the heat transfer process where heat energy is transferred by particles colliding with adjacent particles, allowing the heat to flow through a material. This occurs mainly in solids, where particles are closely packed and can transfer energy through direct contact.
In what process is heat transferred through matter by collisions between particles?
Conduction is the process by which heat is transferred through matter by collisions between particles. It occurs in solids, liquids, and gases. Heat travels from regions of higher temperature to regions of lower temperature through direct contact between particles.
What is the short definition for conduction?
Conduction is the transfer of heat through a material without any movement of the material itself. This process occurs when vibrating particles pass on their energy to neighboring particles.
