Free Time and Temperature 02 Practice Test - 5th Grade
Question 1
If it is 4 hours 15 minutes after midday, the time will read:
4:15 AM
16:15
12:15 PM
14:15
SOLUTION
Solution : B
4 hours 15 minutes after midday (12 noon) is:
12:00 4:15–––––––16:15––––––– or 4:15 pm
Question 2
What is the instrument used to measure body temperature?
Barometer
Thermometer
Clinical thermometer
Thermograph
SOLUTION
Solution : C
A clinical thermometer is used to record body temperature.
Question 3
This clock is 15 minutes fast. What is the correct time?
10:50
10:55
10:15
10:20
SOLUTION
Solution : A
Time an clock = 11:05
Clock is 15 minutes fast
Hence, go 15 minutes backwards to get the right time
[1 hours = 60 minutes 60 + 5 = 65 minutes]
Question 4
8 minutes + 6 minutes - 2 minutes =
270 seconds
800 seconds
740 seconds
720 seconds
SOLUTION
Solution : D
8 + 6 - 2 = 14 - 2 = 12 minutes
1 minute = 60 seconds
∴ 12 minutes = 12 × 60 = 720 seconds
Answer = 720 seconds
Question 5
Water freezes at ____.
100∘C
0∘C
37∘C
20∘C
SOLUTION
Solution : B
Freezing point of water = 0∘C. At this temperature, water turns to ice.
Question 6
6 hours after 9:45 AM is:
3:45 PM
12:45 AM
Noon
1:00 PM
SOLUTION
Solution : A
6 hours after 9:45 AM is
9:45+6:00–––––––– 15:45––––––––
15:45 when converted to 12-hour time format is 3:45 PM.
Question 7
3 hours 10 minutes - 2 hours 55 minutes =
900 seconds
1200 seconds
600 seconds
450 seconds
SOLUTION
Solution : A
1 minute = 60 seconds
∴ 15 minutes = 60 × 15 = 900 seconds
Question 8
A train leaves Bengaluru at 22:35 hours and reaches Chennai after 6 hours 10 minutes. At what time did the train reach Chennai?
4:35 AM
5:35 AM
4:45 AM
5:00 AM
SOLUTION
Solution : C
Time train leaves Bangalore = 22:35 hours or 10:35 PM
Time of travel = 6 hours 10 minutes
10:35 PM to 4:35 AM is 6 hours
35 + 10 = 45
Hence, the train reaches at 4:45 AM
Question 9
In a chemistry lab, 2 reactions are taking place each in 2 beakers. One at 149∘ F (R1) and another at 70∘ C (R2). Which reaction occurs at a higher temperature?
R1
R2
both occur at same temperature
cannot say
SOLUTION
Solution : B
R1 ∘C = (∘F−32)×59
∘F = 149
∘C = (149−32)×59=117×59
∘C = 13 × 5 = 65∘ C
R1 proceeds at 65∘ C
R2 proceeds at 70∘ C
Answer : R2 at 70∘ C is at a higher temperature
Question 10
The time duration from 23:40 to 01:10 is ____ minutes less than the time duration from 14:35 to 17:05.
40 minutes
30 minutes
60 minutes
35 minutes
SOLUTION
Solution : C
a) 23:40 to midnight (00:00) = 20 minutes
midnight (00:00) to 1:10 = 1 hour 10 minutes
∴ 23:40 to 1:10 = 1 hour 10 minutes + 20 minutes = 1 hour 30 minutes
b) 14:35 to 17:05is 2 hours 30 minutes
Difference in the time
H Mins 2:30− 1:30––––––––– 1:00–––––––––
1 hour = 60 minutes
