If a beaker of water is placed under a broiler so that the heating coil is above the beaker. It is observed that only the surfac

e layer boils. The water at the bottom of the beaker remains close to the initial temperature of the water. Which of the following statements is the most reasonable conclusion to be drawn from these observations?
a) Water is a poor conductor of heat.
b) The sample must contain impurities.
c) Water is easily heated by radiation.
d) Water exhibits anomalous thermal behavior.
e) The molecular motion in the sample is not random.

Answer:

a

Explanation:

The most reasonable conclusion of the above phenomenon is that water is a poor conductor of heat. Basically water is an insulator. The heat from surface to the bottom of the beaker will take a lot of time. Moreover, no convection current is formed so, heat might not even reach the bottom surface. Hydrogen bonding also play a vital role in determining the thermal properties of water.

hence option A is correct

If a calorie is equivalent to 4.184 joules how many joules are contained in 250 kg calories slice of pizza
Andreyy89
In order to answer this, we will set up a simple ratio as such:

1 calorie = 4.184 joules

1 kilocalorie = 1000 calories

1 kilocalorie = 4,184 joules

250 kilocalories = x joules

Cross multiplying the second and third equations, we get:

x joules = 4,184 * 250

250 kilocalories are equivalent to 1,046 kJ
