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

a metal sample has a mass of 7.56 g. the sample is placed into a graduated cylinder previously filled with 20.00 mL of water. If

PtichkaEL [24]

Answer:

4.5g/ml

Explanation:

metal sample has a mass = 7.56 g

cylinder previously filled with water = 20.00 mL

final volume in the cylinder = 21.68 mL

$density = \frac{mass}{V_f - V_i}$

$density = \frac{7.56}{(21.68 - 20.00)}$

density = 4.5g/ml
