Correct answer is D
Quantity of heat = ml
= 10 x 80
= 800 cal
A temperature 20°C is the same as
36oF
68oF
11.1oF
43.1oF
25oF
Correct answer is B
212°F ... 100°C
\(\theta\)°F ... 20°C
32°F ... 0°C
\(\frac{\theta - 32}{212 - 32}\) = \(\frac{20 - 0}{100 - 0}\)
180 = 5(\(\theta\) - 32)
5\(\theta\) = 180 + 160 = 340
\(\theta\) = 68°F

the tension in the string decreases as the solid is lifted
the mass of the solid has increased
the solid apparently weighs less when completely immersed in water than when partially immersed
part of the solid still in water is exerting more force on the string
the solid is no longer in equilibrium with water
