The air in a balloon with a volume of 25.0 liters is heated from 20° C to 60° C. If the pressure stays the same, what will be th
Nesterboy [21]

Answer:

New volume of the balloon will be 28.4 L.

Explanation:

As the amount of gas and pressure of the gas remains constant therefore in accordance with Charles's law:

                                          \frac{V_{1}}{T_{1}}=\frac{V_{2}}{T_{2}}

where V_{1} and V_{2} are volume of gas at T_{1} and T_{2} temperature (in kelvin scale) respectively.

Here V_{1}=25.0L, T_{1}=(273+20)K=293K and T_{2}=(273+60)K=333K

So V_{2}=\frac{V_{1}T_{2}}{T_{1}}=\frac{(25.0L)\times (333K)}{293K}  = 28.4 L

So new volume of the balloon will be 28.4 L.

Which one of these is the accepted name for the compound n2o5?
Leya [2.2K]
C is the correct answer. For nonmetal-nonmetal compounds, use the Greek prefixes

Mono - 1
Di - 2
Tri - 3
Tetra - 4
Penta - 5
Hexa - 6
Hepta - 7

And so on...

The reason D is not right is because a and o cannot be next to each other in between prefix and element.

Hope this helps!

Why do you think radioactive decay is measured in half lives, based on the characteristics of the graph.
GREYUIT [131]
The radio active decay of a substance or any chemical is measured in half-lives because of the period where there are significant changes in the amount of the chemicals. The amount of chemical is almost halved in the next period as is suggested by the given graph.

If the point of the nail can be approximated as a circle with a radius 2.00×10^-3m What is the pressure in MPa exerted on the wa
Natasha_Volkova [10]

Answer:

8.28 MPa

Explanation:

From the question given above, the following data were obtained:

Radius (r) = 2×10¯³ m

Force applied (F) = 104 N

Pressure (P) =?

Next, we shall determine the area of the nail (i.e circle). This can be obtained as follow:

Radius (r) = 2×10¯³ m

Area (A) of circle =?

Pi (π) = 3.14

A = πr²

A = 3.14 × (2×10¯³)²

A = 3.14 × 4×10¯⁶

A = 1.256×10¯⁵ m²

Next, we shall determine the pressure. This can be obtained as follow:

Force applied (F) = 104 N

Area (A) = 1.256×10¯⁵ m²

Pressure (P) =?

P = F / A

P = 104 / 1.256×10¯⁵

P = 8280254.78 Nm¯²

Finally, we shall convert 8280254.78 Nm¯² to MPa. This can be obtained as follow:

1 Nm¯² = 1×10¯⁶ MPa

Therefore,

8280254.78 Nm¯² = 8280254.78 Nm¯² × 1×10¯⁶ MPa / 1 Nm¯²

8280254.78 Nm¯² = 8.28 MPa

Thus, the pressure exerted on the wall is 8.28 MPa
