Response: In transverse waves, the movement occurs perpendicular to the vibration source.
In contrast, longitudinal waves oscillate parallel to the source of vibration.
Both types share a common aspect: they facilitate energy transfer within the respective wave forms.
Clarification:
Among the listed options, the one indicating a chemical property is B. Water does not ignite, whereas gasoline is capable of burning. This distinction arises because both combustion and flammability are categorized as chemical properties.
Response:
The name of the compound is calcium phosphide.
Clarification:
Calcium phosphide is a salt-like substance formed from calcium and phosphorus in a 2:5 ratio. It is characterized by its red-brown crystalline appearance.
This compound is utilized as a rodenticide for exterminating rats.
Additionally, it can be employed in fireworks.
Response: 670K
Rationale:
Provided data includes:
Initial volume of gas V1 = 1.22 L
Initial temperature T1 = 286 K
Final volume V2 = 2.86 L
Final temperature T2 =?
As temperature and volume are interrelated when pressure remains constant, apply Charles' law:
V1/T1 = V2/T2
1.22 L/286 K = 2.86 L/ T2
Cross multiplication yields:
1.22 L x T2 = 286 K x 2.86 L
1.22T2 = 817.96
Solving for T2:
1.22T2/1.22 = 817.96/1.22
T2 = 670.459 K (rounded to the nearest whole number is 670 K)
Therefore, the gas temperature is 670 Kelvin
