<u>Answer:</u> The increase in temperature is 7.14°C
<u>Explanation:</u>
To calculate the change in temperature, we use the equation:
where,
q = heat absorbed = 14.5 kJ = 14500 J (Conversion factor: 1 kJ = 1000 J)
m = mass of water = 485 g g
c = specific heat capacity of water = 4.184 J/g.°C
= change in temperature = ?
Putting values in above equation, we get:
Hence, the increase in temperature is 7.14°C
Four sodium ions and four chloride ions
Ans) 1.3 bison/mile
Soln:} See according to the question, Yellowstone National Park has an average of about 4500 bison living in it.
Area covered by Yellowstone park is 3472 miles.
So, to find the density of bisons living in Yellowstone Park we have to divide the no. of bisons by given area.
= 4500/3472
which is approximately 1.3 bisons per mile.
Therefore option a) is correct
Hope it helps!!!
Answer:
table A
Explanation:
its table A because it requires less force push. the less force used the less friction there is.
the less friction there is the more smooth a surface is.
