Answer:

The final temperature is equal to 240 K or -33.15°C

Explanation:

Given that,

Initial temperature of the gas, T₁ = 47°C = 320 K

Initial pressure, P₁ = 140 kpa

Final pressure, P₂ = 105 kpa

We need to find the final temperature if the volume remains constant.  The relation between temperature and pressure is given by :

P\propto T

or

\dfrac{P_1}{P_2}=\dfrac{T_1}{T_2}\\\\T_2=\dfrac{P_2T_1}{P_1}\\\\T_2=\dfrac{105\times 320}{140}\\\\T_2=240\ K\\\\T_2=-33.15^{\circ} C

So, the final temperature is equal to 240 K or -33.15°C.

Answer:

A. H3O+/OH−

Explanation:

A conjugate acid-base pair are a pair of molecules that differ in 1 H⁺

A. The conjugate pair of H₃O⁺ = H₂O not OH⁻

B. The conjugate pair of NH₄⁺ is NH₃

C. The conjugate pair of C₂H₃O₂⁻ is HC₂H₃O₂

D. The conjugate pair of H₂SO₃ is HSO₃⁻

Why do sea turtles rely on instincts more than mammals do?
qwelly [4]

Answer:

Mammals do not have instincts, so they must learn all their behaviors from their parents in order to survive.

Sea turtles must survive on their own, while mammals spend time with their parents and learn how to survive as they grow.

Sea turtles are less intelligent than mammals and, thus, cannot learn new behaviors from their parents.

What material beats and lets you get though all of earth’s layers?
Goryan [66]

Seismic waves

Explanation:

Seismic waves are disturbances that transmits energy elastically and let's scientist have a glimpse of the interior of the earth.

These waves can pass through any component layer of the earth due to their unique properties.

There are four types of seismic waves but the two body waves are the most important in studying the earth's interior.

  • Seismic p-waves can pass through any earth materials as they are longitudinal waves.
  • Seismic s-waves are shear waves and can only pass through solids. liquids and gases cannot be sheared.
