Explain why conduction and convection cannot take place in an airless vacuum like in outer space?
Conduction and convection require the presence of a medium (such as air or water) for the transfer of heat. In a vacuum, there is no medium to transfer heat, so conduction and convection cannot occur. Heat in a vacuum can only be transferred through radiation.
How do you explain the difference between conduction convection or radiation can transfer heat explain?
It's a different way to transfer heat. One object emits electromagnetic radiation (for example, infrared - though it depends on the temperature); another object absorbs it. Heat transfer through radiation can occur in empty space; with conduction and convection, that's not possible.
Can you explain the three modes of heat transfer - conduction, convection, and radiation - and provide examples of each?
The three modes of heat transfer are conduction, convection, and radiation. Conduction: This is the transfer of heat through direct contact between objects. For example, when you touch a hot pan, heat is transferred from the pan to your hand through conduction. Convection: This is the transfer of heat through the movement of fluids or gases. An example of convection is when warm air rises and cool air sinks, creating a convection current. Radiation: This is the transfer of heat through electromagnetic waves. An example of radiation is the heat you feel from the sun, which travels through space without the need for a medium.
How do the principles of convection conduction and radiation explain how water in a pan gets hot?
Convection occurs as warmer water particles rise, transferring heat to cooler particles below. Conduction happens as the heat travels from the stovetop to the bottom of the pan, heating the water through direct contact. Radiation occurs as heat energy from the stove is emitted in the form of infrared radiation and warms the water and the pan.
Explain how water can transfer energy by conduction and by convection?
In conduction, water molecules pass energy through direct contact with neighboring molecules, transferring it without moving the water itself. In convection, energy transfer occurs through the movement of water molecules, as warmer water rises and cooler water sinks, creating a circulation pattern that distributes the energy throughout the water body.

Explain how friction is involved in energy transformation?
Friction creates heat - heat travels by convection, conduction or radiation.

Explain why heat doesnt reach your hand by means of convection and conduction?
I can't explain why it doesn't, because it does.Take a 100W incandescent light bulb, lit up.Place your hand a few feet to the side of it; you receive heat by radiationPut your hand a few feet above it; now you get heat by convection as well.Put your hand touching the top; now you get heat by conduction as well.

Explain two ways that earths atmosphere gets heated?
by convection and conduction
Explain how thermal energy moves in gases compared to the way it moves in soilds?
In gases mainly by convection, that is by bulk movement of molecules of the gas. In solids by conduction, that is by contact between atoms of the material.
What is an air particle diagram?
Particle diagrams are drawings or representations of what atoms, molecules, compounds, mixtures, etc. Ask your Chemistry Teacher for more questions. Particle diagrams are drawings or representations of what atoms, molecules, compounds, mixtures, etc. Ask your Chemistry Teacher for more questions.

With block diagram explain the architecture of DRAM?
explain DRAM architecture with block diagram?
Distinguish between valence and conduction electron hence explain the mechanism of electrons heat and heat transfer in conduction?
Why is conduction important?
What are the three way thermal energy can be transferred?
The pat answer is conduction, convection and radiation. A link is provided below that explains each one. It's in the Wikipedia post on heat transfer, a pillar of thermodynamics.well the 1 of the 3 ways is soundconduction, convection, and radiation. the Holt science textbooks explain everything!
