Which is the correct order of materials in terms of reflectivity from least to greatest?
Black asphalt, brown soil, beige sand, white paper is the correct order of materials in terms of reflectivity, from least to greatest.
Which best explains why Greg’s hands get warm?
Which best explains why Greg’s hands get warm as he holds a bowl of hot soup? Heat energy is created from the thermal energy in Greg’s hands. Heat energy is absorbed by the soup from Greg’s hands. Thermal energy from the soup moves to Greg’s hands.
Which best explains why a black T shirt gets warmer?
A black object can do just that, where it absorbs visible light, but then due to the molecular vibrations, radiate that back as IR/heat. Your dark t-shirt absorbs more visible/UV than lighter ones, and it gets hot and also radiate IR back out. That’s why it feels hotter.
What is heat we feel from the sun?
Thermal Energy: Radiation, Convection, Conduction
| Question | Answer |
|---|---|
| Heat we feel from the sun: | radiation |
| Heat you feel when you touch a hot stove: | conduction |
| Heat you feel when you put your hands ABOVE a fire: | radiation |
| My spoon is hot after leaving it on the pot that was on the stove: | conduction |
What kind of heat does the sun produce?
Solar radiation is created by nuclear fusion reactions in the sun’s core, which causes it to emit a large amount of electromagnetic radiation, mostly in the form of visible light. This radiation is the energy that heats the Earth.
What are the three types of heat transfers?
The Three Mechanisms of Heat Transfer: Conduction, Convection, and Radiation.
Is melting of ice a convection?
Everyday Examples of Convection boiling water – When water boils, the heat passes from the burner into the pot, heating the water at the bottom. This hot water rises and cooler water moves down to replace it, causing a circular motion. ice melting – Ice melts because heat moves to the ice from the air.
Which best defines energy?
Answer: Energy is the ability to do work.
Which material most likely gets the warmest when placed in the sun?
The correct answer is letter c, brown mulch.
Which best explains how thermal energy is transferred?
Which best explains how thermal energy is transferred when someone holds a hand above a fire? It is being transferred by radiation because the hand is not in the path of rising air. It is being transferred by radiation because the hand is in the path of rising air.
Which material is typically used as a thermal insulator?
Thermal insulator : It is a type of material that reduces the transfer of heat between the object in thermal contact. For example : polystyrene foam, water, wool, plastic, ceramic, wood. Hence, the materials typically used as thermal insulators are, foam, ceramic, wood and plastic.
Can humans feel heat?
The sensation of heat comes from nerve-endings that detect the temperature of the skin. The temperature of the skin increases when heat energy flows into the skin. This raises your skin temperature, and you feel the sensation of heat.
How does the sun burn without oxygen in space?
The Sun does not “burn”, like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core. Hydrogen really doesn’t burn, it fuses, into helium. So no oxygen is required!
Does the sun give us oxygen?
Nothing is more important to us on Earth than the Sun. Without the Sun’s heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.
What does the sun burn for fuel?
The Sun produces a large amount of energy by combining very light elements such as hydrogen to heavier elements such as helium and then lithium, oxygen, carbon, right up to iron.
Is our sun blue?
So one might say that the sun is blue-green! This maximum radiation frequency is governed by the sun’s surface temperature, around 5,800K. Because though the sun emits strongest in the green part of the spectrum, it also emits strongly in all the visible colors – red through blue (400nm to 600nm).
What is the closest anyone has gotten to the sun?
On the final three orbits, Parker Solar Probe flies to within 3.8 million miles of the Sun’s surface — more than seven times closer than the current record-holder for a close solar pass, the Helios 2 spacecraft, which came within 27 million miles in 1976, and about a tenth as close as Mercury, which is, on average.
Can anything touch the sun?
NASA’s Parker Solar Probe is the first-ever mission to “touch” the Sun. The spacecraft, about the size of a small car, travels directly through the Sun’s atmosphere –ultimately to a distance of bout 4 million miles from the surface.
