The diagram shows an iron spoon is placed into a hot soup.
After some time, the temperature of the iron spoon and the soup become the same.
What is the concept that describes the situation?
The diagram shows two blocks of copper \(\text P\) and \(\text Q\) which are in contact.
The initial temperature of \(\text P\) is \(60^\circ \text C\) while the initial temperature of \(\text Q\) is \(30^\circ \text C\).
Which of the following statement is true while \(\text P\) and \(\text Q\) are in thermal equilibrium?
(A)
The rate of heat flow from block \(\text P\) to block \(\text Q\) > The rate of heat flow from block \(\text Q\) to block \(\text P\)
(B)
The rate of heat flow from block \(\text P\) to block \(\text Q\) = The rate of heat flow from block \(\text Q\) to block \(\text P\)
(C)
The rate of heat flow from block \(\text P\) to block \(\text Q\) < The rate of heat flow from block \(\text Q\) to block \(\text P\)
The diagram shows the distance between the ice point and the steam point of the mercury thermometer rod after it is dipped in liquid X.
What is the temperature of the liquid X?
(A) \(30.7 ^\circ \text C\)
(B) \(29.8 ^\circ \text C\)
(C) \(28.7 ^\circ \text C\)
(D) \(27.8 ^\circ \text C\)
Which of the following is a characteristic that causes alcohol to be improperly placed as a liquid in a thermometer?
Do not attach to the glass wall
It is opaque
Reacts very slowly to temperature
The diagram shows a graph of length against the temperature of a thermometer placed in liquid \(\text Z\).
Calculate the temperature of liquid \(\text Z\).
(A) \(16.24 ^\circ \text C\)
(B) \(17.24 ^\circ \text C\)
(C) \(18.24 ^\circ \text C\)
(D) \(19.24 ^\circ \text C\)
There is something wrong with this question.
