The relative humidity is 100%.
To find the answer, we have to know about the relative humidity.
<h3>What is the relative humidity?</h3>
- The amount of water vapor in the air is referred to as humidity.
- The gaseous and invisible condition of water is called water vapor.
- Humidity can be expressed in a variety of ways, including absolute humidity, relative humidity, mixing ratio, and dew point temperature.
- Relative humidity can be expressed as,
- Here, it is given that, the vapor pressure is the same as the saturation vapor pressure, thus,
Thus, we can conclude that, the relative humidity is 100%.

Answer:
a) 0.0483 mol
b) 232 °C
Explanation:
Ideal gas law:
PV = nRT
where P is absolute pressure,
V is volume,
n is number of moles,
R is universal gas constant,
and T is absolute temperature.
a) Given:
P = 1.20×10⁵ Pa
V = 1.00 L = 1.00×10⁻³ m³
T = 25.8 °C = 298.95 K
PV = nRT
(1.20×10⁵ Pa) (1.00×10⁻³ m³) = n (8.314 m³ Pa / mol / K) (298.95 K)
n = 0.0483 mol
b) Given:
P = 1.013×10⁵ Pa
V = 2.00 L = 2.00×10⁻³ m³
n = 0.0483 mol
PV = nRT
(1.013×10⁵ Pa) (2.00×10⁻³ m³) = (0.0483 mol) (8.314 m³ Pa / mol / K) T
T = 505.73 K
T = 232 °C
Answer:
Cumulonimbus
Hail development. Hail is a type of strong precipitation, which is shaped in rainstorms mists (Cumulonimbus). Tempests mists comprises of beads of fluid water (at temperatures lower than 0°с, the beads can be in a thermodynamically instable supercooled condition) and ice gems
Explanation:
The linear speed of the pepperoni is 0.628 m/s. Its direction is tangential to the circle.
We know that;
v = rω
r = radius of the piece = 10 cm or 0.1 m
ω = angular velocity
We have to convert 60 revolutions per minute to radians per second
1 rev/min = 0.10472 rad/s
60 revolutions per minute = 60 rev/min × 0.10472 rad/s/1 rev/min
= 6.28 rad/s
v = 0.1 m × 6.28 rad/s
v = 0.628 m/s
The direction of this velocity is tangential to the circle.
