Answer:
The new pressure is 0.5 atm
Explanation:
Step 1: Data given
Volume of oxygen = 300 mL = 0.300 L
Pressure = 1.00 atm
Temperature = 300 K
The volume increases to 1000mL = 1.00 L
The temperature increases to 500 K
Step 2: Calculate the new pressure
(P1*V1)/T1 = (P2*V2)/T2
⇒with P1 = the initial pressure = 1.00 atm
⇒with V1 = the initial volume = 0.300 L
⇒with T1 = the initial temperature = 300 K
⇒with P2 = the new pressure = TO BE DETERMINED
⇒with V2 = the increased volume = 1.00 L
⇒with T2 = the increased temperature = 500 K
(1.00 atm* 0.300 L)/300 K = (P2 * 1.00L) / 500 K
P2 = (1.00 *0.300 * 500) / (300 *1.00)
P2 = 0.5 atm
The new pressure is 0.5 atm
Answer:
= 27Ω
Explanation:
The voltage of a device = Resistance × Current
V=RI
Making R the subject of the formula we have R= V/I
Thus resistance = Voltage/ Current
V= 81 V
I = 3 A
Using these values in the formula for resistance we can then find the resistance of the device as follows.
R = 81 V/ 3 A
= 27Ω
Air is the only one with capability to have speed more than what we think.
Boyle's law which plays a major role in the kinetic-theory states that Volume and Pressure are inversely proportional
