Bromine vapour is heavier than air. even so it's spreads upwards in the experiment above. Why?

Andrews [41]

Answer:

Bromine is heavier than air in terms of its atomic weight. Look at the periodic table bromine is lower than oxygen, nitrogen, etc. bromine in its gaseous phase will still float in air. <em>This is due to the fact that gaseous bromine takes up a wide volume of space while having little mass.</em>

If you traveled one mile at a speed of 100 miles per hour, and another mile at a speed of 1 mile per hour, your average speed wo

salantis [7]

Answer:

The average speed is 1.98 mile per hour.

Explanation:

you traveled one mile at a speed of 100 miles per hour

So, the distance travelled by you is 1 mile

The speed is given by,

Speed = distance/ time

time = distance / speed

time = 1 / 100

time = 0.01 hour

Now next mile you travel at speed 1 mile per hour.

The speed is given by,

Speed = distance/ time

time = distance / speed

time = 1 / 1

time = 1 hour

Total distance = 1 mile + 1 mile = 2 mile

Total time = 1 hour + 0.01 hour = 1.01 hour

Average speed is given by,

Average speed = $\frac{total distance}{total time}$

Average speed = $\frac{2}{1.01}$

Average speed = 1.98 mile per hour

The average speed is 1.98 mile per hour.

1.0 liter of 20c water is mixed with 4 liters of 40c water. What will be the temperature of this mixture

Virty [35]

Answer:

36°C

Explanation:

Heat gained by the cold water = heat lost by the warm water

mCΔT = mCΔT

(1000 g) (4.184 J/g/K) (T − 20°C) = (4000 g) (4.184 J/g/K) (40°C − T)

1000 (T − 20°C) = 4000 (40°C − T)

T − 20°C = 4 (40°C − T)

T − 20°C = 160°C − 4T

5T = 180°C

T = 36°C
