There are two identical object A and B which are in thermal contact. The initial temperature of A and B are 60°C and 20°C respectively. Which statement is correctly about M and N when the thermal equilibrium achieved?
Temperature A is higher than B
Temperature B is higher than A
Net rate of heat flow between A and B is not zero
Net rate of heat flow between A and B is equal to zero
Diagram shows a saucer. Wan Ying order a cup of hot coffee in a Kopi Tiam. The hot coffee is served with a saucer. which of the following statement explain the function of the saucer
The waiter can carry the cup easily
So the coffee can reach thermal equilibrium easily
To prevent the coffee to reach thermal equilibrium easily
so Wan Ying can drink the coffee faster
Alice Liew is drinking her lovely chicken soap. She place the spoon into the bowl of soup at 95°C. Which statement is correct when thermal equilibrium is reached?
Temperature of the soup unchanged
Temperature of the spoon is unchanged
No heat flow between soup and spoon
Soup and the spoon has the same temperature
Anneliese Joelle Then is pouring he hot soup into a bowl. Which statement is correct
Net heat flow from the hot soup to the bowl
Net heat flow from the bowl to the soup
heat flows only from hot soup to the bowl
Net heat flow is zero
Kendrick Tang is having a high fever, he uses cold towel to put on his forehead because
Heat flow faster from the towel to the forehead
Heat flow faster from the forehead to the towel
Net heat flow is equal to zero
His mother ask him to do so
Mercury is used in the liquid in glass thermometer. which of the following statement is wrong
It has high melting point and low boiling point
Opaque
It expand uniformly when heated
good heat conductor
The sensitivity of the liquid in glass thermometer can be increase by
longer the stem
use a wider capillary tube
use a thicker glass at steam
use a thinner glass at the bulb
If liquid in glass thermometer shows the length of 4cm when placed in the ice cube. 29cm showed when it is placed into the boiling water. 14cm shown when the thermometer is placed at the warm liquid. Calculate the temperature of the warm liquid
30°C

50°C
60°C
A thermocouple is placed used to determine the temperature of a drink. When the 2 ends is place at in ice cube and boiling water, there is 15mA of current flow through the thermocouple. But when the 2 ends is place into ice cube and the drink. The current flow through the thermocouple is only 8mA. Find the temperature of the drink.
