Chemistry

1 answer:

makkiz [27]3 years ago

4 0

Answer:

c. higher than other liquids

Explanation:

As many other anomaly in water, heat capacity is consequence of relatively strong hydrogen bonds. Because of these bond, molecules of water need more energy (than many others liquids) to increase their movement (vibration) and, finaly, to increase temperature of water.

Rory answered that absolute zero is 0°K. Is this answer correct? Explain why or why not.

Ierofanga [76]

Answer:

Yes, this answer is correct.

Explanation:

Absolute zero is -273.15 degrees celsius

T= Tc+273.15

T is the kelvin temperature

Tc is the temperature in degrees celsius

substitute;

T= -273.15 + 273.15

T=0 K

A steel tank contains carbon dioxide at a pressure of 13.0 atm when the temperature is 34oC. What will be the internal gas press

morpeh [17]

Answer:

D. 15.8atm

Explanation:

Given parameters:

Initial pressure = 13atm

Initial temperature = 34°C = 34 + 273 = 307K

Final temperature = 100°C = 100 + 273 = 373K

Unknown:

Final pressure = ?

Solution:

To solve this problem, we apply a derivation of the combined gas law taking the volume as a constant.

The expression is shown mathematically below;

$\frac{P_{1} }{T_{1} }$ = $\frac{P_{2} }{T_{2} }$

P and T pressure and temperature values

1 and 2 are initial and final states

Insert the parameters and solve for T₂;

$\frac{13}{307}$ = $\frac{P_{2} }{373}$

P₂ = 15.8atm

If you pump air into cycle tyre a slight warming effect is noticed at valve stem why

Mashutka [201]

As the air molecules move through the valve they have friction as they hit the walls, and its this friction that causes it to heat up.

Gain or lose.
The exchange of electrons in chemical bonding seeks to fulfill the octet rule. There are some exceptions, such as with hydrogen and helium, whose valence shells have a capacity of two electrons.
