3.4 x 10-5m3
4.3 x 10-5m3
3.4 x 10-5m3
3.4 x 10-3m3
3.4 x 10-2m3
Correct answer is C
V = \(\frac{m}{p}= \frac{170}{8.5 x 10^{-3}}\) = 0.02
= \(\Delta\)\(\frac{\delta V}{V \delta T}\)
\(\delta V\) = \(\Delta\) x V x \(\delta\)T
= 5.7 x 10-5 x 0,02 x 30
= 0 3.42 x 10-5
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
