For holding small amounts of chemicals for heating and mixing liquids

Question 14

Function of beaker

Answer 14

For containing chemicals for heating and collecting and holding liquids

Question 15

Function of boiling tube

Answer 15

For containing chemicals for heating and collecting and holding of liquids

Question 16

Function of conical flask

Answer 16

For containing and mixing chemicals when heating is not required

Question 17

Function of round-bottomed flask

Support apparatus which cannot be heated directly with the flame of a Bunsen burner

Question 25

Function of a tripod stand

Answer 25

Support apparatus when heating

Question 26

What is a zero error

Answer 26

When an instrument gives a non-zero reading when the measured quantity should be zero

Question 27

What is a parallax error

Answer 27

When the marking on an instrument is viewed from the wrong angle

Question 28

What is a random/unpredictable error

Answer 28

Caused by unknown and unpredictable changes is the experiment resulting in imprecise measurements

Question 29
