Answer:

hey. I remember learning about this and asking my teacher why the heck would you think about all that instead of just eating the food XD.....

but the Heat from the burner warms the pan by conduction. The liquid soup is warmed by convection currents. ... Metal is a good conductor of heat. Theheat energy moves from the hot liquid through the spoon by conduction.

2) Ge is a neutral atom because it doesn't have any charge.

Germanium has 32 electrons and 32 protons because its atomic number is 32.

Be careful with that.

Neutral atoms have the same numbers of electrons and protons.

A sample of gas contains 3.0L of nitrogen at 320kPa. What volume would be necessary to decrease the pressure at 110kPa

Phoenix [80]

Answer:

$V_{2} = 8.92 L$

Explanation:

We have the equation for ideal gas expressed as:

PV=nRT

Being:

P = Pressure

V = Volume

n = molar number

R = Universal gas constant

T = Temperature

From the statement of the problem I infer that we are looking to change the volume and the pressure, maintaining the temperature, so I can calculate the right side of the equation with the data of the initial condition of the gas:

$P_{1} V_{1} =nRT$

$320Kpa*0.003m^{3} =nRT$

$1000L = 1m^{3}$

$nRT= 0.96$

Now, as for the final condition:

$P_{2}V_{2}=nRT$

$P_{2} V_{2} =0.96$

clearing $V_{2}$

$V_{2} =\frac{0.96}{P_{2} }$

$V_{2} =0.00872m_{3}$

$V_{2} = 8.92 L$

1. What causes wind? *

Gelneren [198K]

Answer:

it's the uneven heating of the region's of the troposphere by the sun the sun warms the air at the equator more than the air at the poles. it causes convention currents large scale patterns of winds that move heat and moisture around the globe. as air rises expands and cools water vapor condenses and clouds develop.

I hope this helps :)
