2.85 x 10-5K-1
1.90 x 10-5K-1
1.86 x 10-5K-1
1.70 x 10-5K-1
1.63 x 10-5K-1
Correct answer is B
\(\alpha\) = \(\frac{\Delta}{3} = \frac{5.7 \times 10^{-5}}{3}\)
= 1.90 x 10-5K-1
The average kinetic energy of the molecules of a perfect gas is directly proportional to the
pressure exerted by the gas
volume of the gas molecule
kelvin temperature of the gas
volume of the gas container
celcius temperature of the gas
Correct answer is C
The average kinetic energy of the molecules of a perfect gas is directly proportional to the Absolute temperature that is the temperature measured using the kelvin scale.
4mm
18mm
30mm
135mm
450mm
Correct answer is C
by interpolation,
\(\frac{100 - 0}{10- 0} = \frac{180 - y}{45 - y}\)
\(\frac{100}{10} = \frac{180 -y}{45 - y }\)
450 - 10y = 180 - y
- 9y = - 270
y = 30mm
An object is heated from 30°C to 57°C. The increase in its temperature on the Kelvin scale is
17k
27k
81k
246k
300k
Correct answer is B
30°C + 273 = 303K
57°C + 273 = 330K
∆T = 330K - 303K
→ 27K
