A change of temperature of 20 C is equivalent to a change in thermodynamic temperature of
Leto [7]

Answer:

20 K

Explanation:

It is given that,

The change in temperature is 20 C.

We need to find the change in thermodynamic temperature.

If teperauture T₁ = 0° C = 0+273 = 273 K

T₂ = 20° C = 20 + 273 = 293 K

The change in temperature,

\Delta T=T_2-T_1\\\\=293-273\\\\=20\ K

So, the change in temperature of 20°C is equivalent to 20 K.

(4) A stainless steel storage tank contains 5 kg of carbon dioxide gas and 7 kg of argon gas. How many kmoles are in the tank?
Elenna [48]

Answer:

0.2886 Kmoles

Explanation:

Number of moles is calculated by dividing mass of element/molecular mass of element

Mass of Carbon Di oxide = 5000 g or 5 kg

Molecular mass of CO2 = 12 + 16×2 = 44 g

No of moles = 5000/44 = 113.6 moles = 0.1136 Kmoles

Mass of argon = 7Kg or 7000 kg

Molecular mass of Argon(Ar) = 40g

No of moles = 7000/40 = 175 moles = 0.175 Kmoles

Total Kmoles = 0.175+0.1136=0.2886 Kmoles

A force is a push or a pull. Under the right circumstances, anything can exert a force.
Sliva [168]

Answer:

Explanation:

the force that you applied caused the notebook to move.

the force applied on the notebook by the table causes it to stop moving.

this is because after sometime the book uses up the force and later the force you applied is less than that of the force by the table.

Please Help!!! It's for a quiz!!
Sphinxa [80]

Answer:

38.8 m/s

Explanation:

Force F(x) = 6 - 2x + 6x²

work

W=\displaystyle\int_{0}^{13.9}F(x)dx=\displaystyle\int_{0}^{13.9}(6-2x+6x^2)dx

=6x-x^2+2x^3|_{0}^{13.9}\\=5261 J

W = mv²/2=7v²/2 = 3.5v² = 5261

v = 38.8 m/s
