Which object is hotter? Multiple Choice -22:49 O Object 1 at T = 0°C Object 3 at T = OK Object 2 at T = 0°F
1 answer:
Answer:
Object 1 is hotter.
Explanation:
Object 1 T=
Object 2 T=0 K
Object 3 T=
Relation between Celcius ,Kelvin and Fahrenheit
K=C+273, .
So now we will convert all in one unit.
Object 1 T=273 K
Object 2 T=0 K
Object 3 T=255.22 K
From above we can say that Object 2 is coolest and object 1 is hottest.
So Object 1 is hotter.

Answer:
C. Equal amounts of gases occupy the same volume at constant temperature and pressure.
Explanation:
As we know by ideal gas law that
now here we have
so as per Avagadro law if the temperature and pressure of the gas is constant then volume of the gas is directly proportional to the number of moles of the gas.
so correct answer will be given as
C. Equal amounts of gases occupy the same volume at constant temperature and pressure.
Answer:
The heat builds pressure
Explanation:
Consider an ideal gas in a closed system (like a gas in a container: in this case, the volume of the gas is fixed). The ideal gas equation states that:
where
p is the gas pressure
V is the gas volume
n is the number of moles of the gas
R is the gas constant
T is the gas temperature
If heat is added to the gas, its temperature T increases. n and R are constant, and V is constant as well (the container does not change its volume), so this means that the pressure of the gas, p, increases as well. The more heat is added, the more the temperature increases, the more the pressure increase: at some point, the pressure against the internal walls of the container will become so strong that the container will explode.
