The most viscous among the choices is D. Honey at room temperature.
Viscosities of liquids typically vary with temperature. The higher the temperature, the lower the viscosity. Among the choices, only motor oil and honey appear to be the most viscous. The clue that helps determined the answer are the words "hot" and "room temperature". Hot motor oil is less viscous, while honey at room temperature is more viscous. Even comparing their viscosities at room temperature, honey already has a higher viscosity than motor oil.
Answer:umm I think it’s B
Explanation:
Answer:
Below.
Explanation:
Because of the hydrogen bonding that occurs in water. Oxygen is more electronegative than sulphur and forms inter molecular bonding between the H+ and O- ions in the water. This does not occur in H2S.
Answer:
P₂ = 607 mmHg
Explanation:
Given data:
Initial volume = 4.5 L
Final volume = 5.6 L
Initial pressure = 756 mmHg
Final pressure = ?
Solution:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
756 mmHg × 4.5 L = P₂ × 5.6 L
P₂ = 3402 mmHg. L/5.6 L
P₂ = 607 mmHg
Answer:
955980 j
Explanation:
Given data:
Mass of water = 423 g
Temperature = 100°C
Amount of energy required = ?
Solution:
For one gram of water heat of energy required to convert it into vapors is 2260 j/g.
Amount of heat required for 423 g.
423 g × 2260 j/g = 955980 j
The amount of energy released when one gram steam is condensed into water is -2260 j.
For 423 g water vapor to condensed energy released.
423 g × -2260 j/g = -955980 j
