Pressure is inversely related to temperature
Answer: a 900 milliliter (ml) pitcher of orange juice at 20 degrees Celsius ( oC)
Explanation:
Thermal energy is the energy possessed by an object by virtue of its temperature. The hotter the substance, the more its molecules vibrate, and therefore the higher its thermal energy.
Thermal energy refers to the sum of kinetic, potential, vibrational ,electronic and rotational energies of the object.
For bodies at same temperature, the body with more molecules will have more thermal energy due to more collisions.
Answer:
OptionA. 2C4H10 + 13O2 —> 8CO2 + 10H20
Explanation:
Butane burns is air (O2) according to the equation:
C4H10 + O2 —> CO2 + H20
Considering the equation, it is evident that it not balanced. Now let us balance the equation as shown below;
There are a total of 4 carbon atoms on the left and 1 carbon atom on the right. It can be balanced by putting 4 in front of CO2 as shown below:
C4H10 + O2 —> 4CO2 + H20
Next, there are 10 hydrogen atoms on the left and 2 hydrogen atoms on the right. Therefore to balance it, put 5 in front of H2O as shown below:
C4H10 + O2 —> 4CO2 + 5H20
Now, there are a total of 13 oxygen atoms on the right and 2 at the left. To balance it, put 13/2 in front of O2
as shown below
C4H10 + 13/2O2 —> 4CO2 + 5H20
Now we multiply through by 2 clear off the fraction and we obtained:
2C4H10 + 13O2 —> 8CO2 + 10H20
No, many liquids have surface tension such as mercury.
This problem can be solved by using ideal gas equation PV=nRT. The unit used in the numbers is already matched so you don't need to convert any of them. The calculation would be:
PV= nRT
102.3 kPa * V = 0.00831 mol *298.15 K* (8.314 L*kPa/mol*K) V= 20.60 L-kPa / 102.3 kPa V= 0.201358 L
