Science Quiz for Junior Groups

When Klaus came home, the temperature values of the ice cream he took out of the boxes and the results he obtained are as shown below. Accordingly, which of the following is wrong?

• The 3rd box is a good heat insulator compared to the 1st box.

• The Ice cream melted because the 2nd box could not prevent the heat transfer from ice cream to air.

• The material from which the 3rd box is made is most likely plastic or wood.

• The material from which the 2nd box is made is most likely metallic.

Which of the results Paul obtained about his experiment is wrong?

• Mass is conserved in physical change

• The substance K has more mass than the substance

• The volume of water soluble substances cannot be accurately measured with a graduated cylinder.

• The substance L is more dense than the substance KLM

Accordingly, which of the following statements is false?

• Only lamp L lights up in connection B1 - C

• In A1 - D3 connection, the bulbs K, L and M light up the same brightness.

• The brightness of the lamp K is equal in connections A1 - B2 and A1 - C3.

• Lamp L does not light in connection A1 - D

What properties should the paint in the circuit maker have?

• III and

• III, IV and V

• II, IV and

• II, IV and V

What could be the reason for so much difference in temperature between the inside and outside of Eskimo houses?

• Solids conduct heat better than gases.

• The heat conduction of still air is lower than the heat conduction of solids.

• As the space between the particles forming the substance increases, the thermal insulation decreases.

• White colored snow blocks reflect sunlight.

Accordingly, at the end of the game, which power plant picture will be seen on the table?

• Solar power plant

• Nuclear power plant

• Wind power plant

• Geothermal power plant

• Only II

• I and II

• II and III

• I, II and III

Accordingly, which of the following information is not correct?

• Z is a terrestrial plane

• X and Y are gaseous planet

• Planet X has a smaller mass than planet

• There is life on planet

• The fur of a scared cat getting upright

• Wilting of a dehydrated plant

• Plants turning towards light

• Watering/salivating at the mouth of a dog that sees meat

• Antifreezes increase the boiling point of the liquid and allow higher coolant temperature.

• It prevents the engine from overheating and extends the life of the engine.

• Solutions freeze at a higher temperature than the pure form of the solvent.

• It decreases the freezing point of the engine cooling water and prevents the engine from being damaged in cold seasons.
