If temperature (T) and amount of gas (n) remain constant, but pressure (P) and volume (V) change, then the ideal gas law: PV = nRT becomes
P1V1 = P2V2 --> (41)(16) = P2 (4)
--> P2 (4) = 656
P2 = 656/4 = 164 kPa
Answer:
4.5 and 1.5
Step-by-step explanation:
4.5+1.5=6
4.5-1.5=3(difference)
B. 54
Because 54+13=67
67+54=121
Answer:
BFC makes this angle add up to 90 degree at BFD
Therefore it becomes complementary to angle CFD
Answer: 36 degrees
Step-by-step explanation:
subtract 5 from 30=25
add 11 to 25
25+11=36
