The energy required to change a solid to liquid at constant temperature is called
thermal capacity
has lower specific heat capacity
latent heat of fusion
latent heat of vaporisation
Correct answer is C
No explanation has been provided for this answer.
0.119oC
0.840oC
1.190oC
8.400oC
Correct answer is A
mgh = mc\(\theta\)
\(\theta = \frac{gh}{c} = \frac{10 \times 50}{4200}\)
= 0.119oC
1100Jkg-1K-1
320Jkg-1K-1
200Jkg-1K-1
176Jkg-1K-1
Correct answer is B
pt = mc\(\theta\)
C = \(\frac{pt}{m \theta}\)
= \(\frac{400 \times 1}{0.5 \times 2.5}\)
= 320Jkg-1K-1
ms\(\theta\) = mv-1
ms = C
ms = s\(\theta\)
ms = c\(\theta\)
Correct answer is B
Q = ms\(\theta\) = c \(\theta\)
ms = C
10.0oC
15.0oC
20.0oC
30.0oC
Correct answer is A
100....180
A......45
0......30
\(\frac{45 - 30}{180 - 30} = \frac{A - 0}{100 - 0}\)
A = \(\frac{15 \times 100}{150} = 10^oC\)
