<h3>(c) Terylene fibres</h3>

Explanation:

<h3>TERYLENE FIBRES </h3>

Terylene Fibres is a crease-resistant, long-lasting material with a low moisture content. Pests like as moths and mildew have no effect on it. As a result, it's utilized to make fabrics that can be washed and wear clothes. It's also mixed with cotton (Terycot) and wool (Terywool) to add durability.

A sample of He gas (3.0 L) at 5.6 atm and 25°C was combined with 4.5 L of Ne gas at 3.6 atm and 25°C at constant temperature in

LenKa [72]

Answer:

$P=3.7atm$

Explanation:

Hello,

In this case, it is possible to determine the pressures of both helium and neon as shown below:

$n_{He}=\frac{P_{He}V_{He}}{RT}=\frac{5.6atm*3.0L}{0.082\frac{atm*L}{mol*K}*298.15K} =0.688molHe\\\\n_{Ne}=\frac{P_{Ne}V_{Ne}}{RT}=\frac{3.6atm*4.5L}{0.082\frac{atm*L}{mol*K}*298.15K}=0.663molNe$

Now, one considers the total moles (addition between both neon's and helium's moles) and the total volume to compute the final pressure as shown below:

$P=\frac{n_TRT}{V_T} =\frac{(0.688+0.663)mol*0.082\frac{atm*L}{mol*K}*298.15K}{9.0L}=3.7atm$

Best regards.

What evidence suggests that four-legged animals came from fish?

cupoosta [38]

Answer:

Paleontologists have uncovered new fossils from Tiktaalik roseae, which, while still a fish, is considered a transitional fossil that also has traits common to the first four-footed animals. This more complete picture of Tiktaalik suggests that the creature had strong, mobile hind fins.

How would you explain the Earth’s atmosphere?

CaHeK987 [17]

<span>The atmosphere is a thin layer of gases that surrounds the Earth. It seals the planet and protects us from the vacuum of space. It protects us from electromagnetic radiation given off by the Sun and small objects flying through space such as meteoroids.</span><span>

So it's like a blanket protecting us but it has air hole/patches where sunlight can get through</span>
