Profundal
profundal zone is the coldest and deepest zone
Answer:
Option D. The water in Glass A is cooler than the water in Glass B; therefore, the particles in Glass A move slower.
Explanation:
Solubilities of solutes are enhanced when the temperature is increased.
From the experiment conducted,
It is evident that glass B temperature is higher than glass A temperature, because the solute dissolves faster in glass B than in glass A . This implies that glass A is cooler than glass B, hence the particles in A will move slower than that in B.
Propane torch is lit inside a hot air balloon during pre-flight preparation because the heat from the touch is needed to heat the cold air inside the balloon, so that the air will expand and become less dense and rise, thus providing a lift for the balloon. This is line with charle's law, which states that, the volume of a fixed mass of ideal gas is directly proportional to the absolute temperature. This law implies that, as the temperature of the air inside the balloon increase, the volume of the balloon also increases.
Answer:
The concentration is 0,2925M
Explanation:
We use the formula
C initial x V initial = C final x V final
11,7 M x 25 ml = C final x 1000 ml
C final= (11,7 M x 25 ml)/1000 ml = 0, 2925 M
(This formula applies to liquid solutions)
Answer:
50 mm
4 ft
36 ft
250 cm
1 L
Explanation:
Centimeter to millimeter:
1 cm is equal to 10 mm.
5cm× 10 mm/1 cm
50 mm
Inches to feet conversion:
1 foot is equal to 12 inches.
48 inch × 1 feet /12 inch
4 feet
Yard to Feet conversion:
1 yard is equal to 3 feet.
12 yd × 3 ft / 1 yd
36 ft
Meter to centimeter:
One meter is equal to 100 cm.
2.5 m × 100 cm / 1m
250 cm
Milliliter to Liter:
One L is equal to 1000 mL.
1000 mL = 1 L
