18. The orbits of planets being elliptical was one the planetary laws developed by

Answer:

Explanation:

Cylinder P is taller than cylinder Q. In fact, it's twice as tall. So if cylinder Q is, let's say, 10 inches tall, cylinder P would be 20 inches tall.

Cylinder P is also wider, but not by a lot. It's only half as wide as cylinder Q. So if cylinder Q has a width of 10 inches, cylinder P would have a width of 5 inches.

Now, let's talk about the insides of these cylinders, how much stuff they can hold. If we filled them up with something, like water, the bigger one (cylinder P) can hold twice as much as the smaller one (cylinder Q).

So, cylinder P can hold more stuff because it's both taller and a little wider than cylinder Q.

Answer: Minerals that are mined for titanium are ilmenite and rutile.

Explanation:

Titanium is the 22nd element of the periodic table. It symbol is "Ti"

The minerals which are mined to extract titanium are ilmenite and Rutile

Titanium is extracted from ilmenite with a process of acid leaching using fluorosilicic acid

Titanium is extracted from rutile by converting it into titanium(IV) chloride, and then reducing it to titanium using either magnesium or sodium.

Therefore, Mineral that are used to mine Titanium are ilmenite and rutile.

The given system is a constant pressure systemwhere the work done is the product of the pressure and the volume change.

• The volume to which the gas expands to is approximately 11 liters

Reasons:

Given parameters;

The original volume, V₁ = 40 cm³

The energy released, E = 950 J

Constant pressure applied, P = 650 torr.

Condition: All energy is converted to work to push back the piston

Required:

The volume to which the gas will expand

Solution;

The work done, W = Energy releases, E = 950 J

Work done at constant pressure, W = P·(V₂ - V₁)

Where;

V₂ - The volume to which the gas will expand

Converting the volume to from cm³ to m³ gives;

V₁ = 40 cm³ = 0.00004 m³

Converting the pressure given in torr to Pascals gives;

650 torr. = 86659.54 Pa.

Therefore, we get;

950 J = 86659.54 Pa. × (V₂ - 0.00004 m³)

Converting to liters gives;

• The volume to which the gas expands, V₂ ≈ 11 liters.

Answer:

The volume needed to expand the gas is = 11 Lit = 11000

Explanation:

Given :

Initial volume Lit.

Energy J = 9.38 Lit × atm.   ⇒ ( 1 Lit×atm. = 101.325 J )

Pressure 650 torr = 0.855 atm. ⇒ ( 1 torr = 0.00132 atm )

In this example we have to be aware of unit conversion system.

From the laws of thermodynamics,

Here in this example, all the energy of combustion is converted into work to push back the piston

Lit =
