Assoli18 [71]

Answer:

The entropy change of carbon dioxide = 0.719 kJ/k

Explanation:

Given:

1.5 m - 3 insulated rigid tank contains 2.7 kg of carbon dioxide at 100 kPa

The objective is to determine the entropy change of carbon dioxide

Formula used:

ΔS=

Solution:

On considering,

C_{P} =0.846 kJ/kg K\\C_V=0.657 kJ/kg k\\

ΔS=mc_{v} lu\frac{p_{2} }{P_{1} }

On substituting the values,

ΔS=2.7*0.657lu\frac{150}{100}

ΔS=0.719 kJ/k

PLEASE HELPP
rodikova [14]

Answer:

Option (C) 1 × 10^−12

Explanation:

Step 1:

Data obtained from the question include:

[H+] = 1x10^−2

[OH−] =?

Step 2:

Determination of [OH−] . This is illustrated below:

[H+] x [OH−] = 1x10^-14

1x10^−2 x [OH−] = 1x10^-14

Divide both side by 1x10^−2

[OH−] = 1x10^-14 / 1x10^−2

[OH−] = 1x10^-12

Therefore, the [OH−] of the solution is 1x10^-12

Explain how ice acts as an agent of erosion and deposition
ratelena [41]

Answer:

Ice is the last major agent of weathering, erosion, and deposition.

Explanation:

Water often seeps into the cracks in rocks. When the temperature drops, the water in the cracks freeze and expand, causing the crack to widen. Eventually, the rock is broken into smaller pieces.
