Answer:
You can feel the heat transfer from a fire and from the Sun. Similarly, you can sometimes tell that the oven is hot without touching its door or looking inside—it may just warm you as you walk by. The space between the Earth and the Sun is largely empty, without any possibility of heat transfer by convection or conduction. In these examples, heat is transferred by radiation. That is, the hot body emits electromagnetic waves that are absorbed by our skin: no medium is required for electromagnetic waves to propagate. Different names are used for electromagnetic waves of different wavelengths: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

Government officials applied rigid caste laws after visiting India.
Answer:
The volume would be 800mL and it shows that it is constant.
Explanation:
Given parameters:
Intial volume of gas V₁ = 800mL
Initial temperature T₁ = -23°C to Kelvin; we use K = °C + 273 = -23 + 273 = 250K
Inital pressure P₁ = 300torr
Final temperature T₂ = 227°C to K = 227 + 273 = 500K
Final pressure P₂ = 600torr
Unknown parameter:
Final volume V₂ = ?
To solve this problem, we use the General gas law or the combined gas law where we assume that n=1, this gives:
= 
Since the unknown is V₂, we make it the subject of the formula:
V₂ = 
V₂ = 
V₂ = 800mL
The pH shows the degree of acidity or alkalinity of a substance. A substance whose pH is greater than 7 is basic. As molecules of water turn into ice, the arrangement of the molecules changes. If my target is to increase the particle motion of a gas without increasing any of it's other properties, then i need to Keep the gas in a fixed container at constant pressure and increase the temperature. A supersaturated solution contains more solute than it can normally hold at a given temperature. Therefore, supersaturation requires the use of powered solute, to increase the saturation point beyond the normal maximum.
The pH scale ranges from 1 - 14 and is a suitable way of determining the extent of acidity or alkalinity of a solution. A solution whose pH ranges from 0 - 6.9 is acidic. A solution whose pH ranges from 8 -14 is basic. A pH of 7 indicates a neutral substance.
Temperature is defined as a measure of the average kinetic energy of the molecules of a body. Therefore, to increase the particle motion of a gas without increasing any of it's other properties, we need to keep the gas in a fixed container at constant pressure and increase the temperature.
The difference between solid, liquid and gaseous states of matter is the arrangement of the molecules. Solid molecules are more closely packed than liquid molecules and liquid molecules are more closely packed than gas molecules. Hence, as a sample of water turns to ice, the arrangement of the molecules changes.
Lastly, supersaturation refers to a situation where a solution contains excess solute at a given temperature. Thus, supersaturation requires the use of powered solute, to increase the saturation point beyond the normal maximum.
