Answer is: temperature of helium is -296,95°C.
The temperature T<span> in degrees Celsius (°C) is equal to the temperature </span>T in Kelvin (K) minus 273,15: T(°C) = T(K) - 273.15.
T(He) = 4,2 K.
T(He) = 4,2 K - 273,15.
T(He) = -268,95°C.
The Celsius scale was based on 0°C for the freezing point of water and 100°C for the boiling point of water at 1 atm<span> pressure.</span>
Answer:
The answer is true
Explanation:
the ovary is a tubular structure and contains ovules
Answer:
Final volume v2 = 0 ml
Explanation:
Given:
Initial temperature = 100°C
Initial volume = 75 ml
Final temperature = 0°C
Find:
Final volume
Computation:
Using Charles law formula;
⇒ V1 / T1 = V2 / T2
Where
⇒ Initial temperature = T1
⇒ Initial volume = V1
⇒ Final temperature = T2
⇒ Final volume = V2
So,
⇒ 75 / 100 = V2 / 0
Final volume v2 = 0 ml
Answer:
T = -28.2 °C
Solution:
Data Given;
P = 1820 mmHg = 2.39 atm
V = 5.12 L
m = 19.4 g
R = 0.0821 atm.L.mol⁻¹.K⁻¹
Calculating moles,
n = 19.4 g ÷ 32 g.mol⁻¹
n = 0.606 mol
Assuming that the oxygen gas is acting perfectly, then according to Ideal Gas Equation,
P V = n R T
Solving for T,
T = P V / n R
Putting values,
T = (2.39 atm × 5.12 L) ÷ (0.606 mol × 0.0821 atm.L.mol⁻¹.K⁻¹)
T = 244.7 K
Or,
T = -28.2 °C
Yes its possible bcz the chemical reaction doesn’t only happen in temperature
