HELPPP PLSS!!
Use the table of temperatures from several areas to complete the statement.
Area | Temperature (ºC)
--------------------------------------
X | 22
-------------------------------------
Y | 18
-------------------------------------
Z | 18
------------------------------------
Air will move from _____.
A. area Y to area Z
B. area Z to area Y
C. area Y to area X
D. area X to area Z
Use the table of temperatures measured in two areas of a house to answer the question.
Area | Temperature (ºC)
----------------|---------------------------
downstairs | 22
----------------|---------------------------
upstairs | 26
Which statement best explains the temperature difference?

B. Energy from the cooler air is transferred upstairs.
C. The cooler air downstairs loses energy to the environment.
D. Warm air rises by convection to the upstairs.
The transfer of heat by direct contact is called _____.
A. kinetic energy.
B. conduction.
C. vibrating molecules.
D. radiation.
Which option is an example of heat transfer by conduction?
A. pavement heating up in the sun
B. air getting warm from a radiator
C. air conditioner cooling the room
D. person getting warm from an electric blanket
TYYYYYYY!!!!!!!!

HOPE IT HELPS
!!
B. Energy from the cooler air is transferred upstairs.
D. Warm air rises by convection to the upstairs.
B. Conduction.
D. Person getting warm from an electric blanket.
ty!!!! @some one i don't know? !!!!
For the first question, to determine the direction of air movement, we need to compare the temperatures in the different areas. Looking at the table, we can see that area Y and area Z have the same temperature of 18ºC, while area X has a higher temperature of 22ºC.
Since air tends to move from areas of higher temperature to areas of lower temperature, the air will move from area X to area Z (D. area X to area Z).
For the second question, we have temperatures measured in two areas of a house: downstairs and upstairs. Downstairs has a temperature of 22ºC, while upstairs has a higher temperature of 26ºC.
The best explanation for the temperature difference is that warm air rises by convection to the upstairs (D. warm air rises by convection to the upstairs).
The transfer of heat by direct contact is called conduction. (B. conduction)
An example of heat transfer by conduction is air getting warm from a radiator. (B. air getting warm from a radiator)
I hope this helps! Let me know if you have any more questions.
