Answer:
Container A is a solution and Container B is a colloid.
Explanation:
Container A is a solution as the tyndall efffect is not present. You cannot see the light bean through the glass.
Container B is a suspension or a colloid as you can see the beam through the glass.
The first option proposes Container A is a colloid...this is not correct
The third option is not true as the tyndall effect is only displayed in container B
The fourth option is not correct the tyndall effect is not present in container A meaning it would not be a suspension or a colloid and you can see the tyndall effect in container B indicating its not a solution
Answer:
Q = 87.31cal
Explanation:
Mass = 57.8g
T1 = 17.0°C
T2 = 43.5°C
Specific heat capacity (c) = 0.057cal/g°C
Q = MC∇T
Q = M*C*(T₂ - T₁)
Q = 57.8 * 0.057 * (43.5 - 17.0)
Q = 3.2946 * 26.5
Q = 87.306 cal
Q = 87.31cal
The acoustic extinguisher works by using sound waves—a type of pressure wave—to push oxygen away from the source of a flame and spread it over a larger surface area. These actions break the fire combustion triangle made up of heat, fuel, and oxygen, the three elements required for a fire to burn.
