An ideal gas has a volume of 18.25 L at a temperature of 15.9 °C. The temperature of the gas is raised to 40.7 °C while the numb

er of moles and the pressure of the gas are kept constant. What is the new volume of the gas (in L)?
B: An ideal gas has a volume of 10.8 L at a temperature of 25.0 °C and a pressure of 60 atm. The pressure of the gas is reduced to 370.0 mmHg, but the temperature and number of moles of the gas are kept constant. What is the new volume of the gas (in L)?

Answer:

V₂ = V₁ / T₁ * T₂ . If you prefer to set the final volume and want to estimate the resulting temperature, then the equation of Charles' law changes to: T2=T1/T1 multiplied by v^2.

The flotation process used in metallurgy involves the separation of gangue from ore.

<h3>How does the flotation process work?</h3>

The various wettability qualities of a material's surface are the foundation of flotation operations. The basic principles of flotation are quite similar to those of a sink and float process, where the materials' relative densities to the medium in which they are deposited determine the basis of the separation.

<h3>What is the process of separating minerals from gangue known as?</h3>

Mineral processing, mineral dressing, or ore dressing are all terms for the process of separating minerals from gangue. It is an important and frequently necessary part of mining. Depending on the type of minerals used, the process may be difficult.

Which is the coal with the highest energy available per unit to burn: lignite, subbituminous, bituminous, or anthracite?
olya-2409 [2.1K]

Answer:

Anthracite

Explanation:

Anthracite produce highest amount of energy than other. It contain 86-97 percent carbon. Bituminous coal contain 45-86 percent carbon.

Subbituminous cola have 35-45 percent carbon while lignite contain 25-35 percent carbon.

Coal is source of many organic materials. It is fossil fuel and form after long period decay of plants. It is formed when trees are buried under earth

about 500 million years ago. The chemical and bacterial reactions take place and plant wood converted into the peat.

Than because of high temperature and pressure inside the earth peat is converted into the coal.

Through other processes it is than used to make the fuels such as coke. coal tar and coal gas.

Coal tar is the source of many organic compounds which are separated through fractional distillation.

About 80% of coal in Pakistan is used to bake the bricks and also used in lime kilns and for domestic purpose.

What is the formula for speed of light?
satela [25.4K]
<span><span>There is no formula. The speed of light is a fundamental constant which appears in other formulas but there’s no formula to compute the numerical value.Well, actually, that’s not quite right. The numerical value in meters per second is known exactly, because we use the speed of light to define the meter. It is: <span><span><span>c=299,792,458 m/s</span><span>c=299,792,458 m/s</span></span> </span>. Exactly. But the thing is — this value is purely an artifact of our unit system. Other unit systems will give other values, so the number value is entirely arbitrary.</span></span>
