Let’s assume that you put a balloon into the freezer. Initially,the balloon had 3.0liters of gas at a pressure of 400kPa and was

at a temperature f 294K. If the balloon is cooled to 277K and it’s volume decreased to 1L, what will the new pressure in the balloon be?

Here, we should use combined gas law which can be derived from combined gas law, “PV=nRT”. Rearranging, we can get PV/T=nR. Then we can set the two states in the problem together to get

P1V1/T1 = P2V2/T2

Then just plug in and solve algebraically.

Hope this helps

Which characteristic of water helps it form droplets?
inessss [21]

Answer: C. High surface tension

Explanation:

Water has high specific heat as it require high heat to raise the temperature of 1 g of water through 1^0C.

Surface tension is the net downward force acting on the surface of liquids due to the cohesive nature of liquids.  

Water molecules are bonded by strong hydrogen bonding between the hydrogen atom and the electronegative oxygen atom making it polar. Thus water molecules present on the surface are strongly attracted by the molecules present below the surface and thus act as a stretched membrane.  

The surface acquires a minimum surface are and thus acquire a spherical shape.

What is the bond between Ca and Cl
gtnhenbr [62]

ionic bond is formed between ca and cl forming molecule cacl2 ca has 2 velancy and cl has one velancy (ca has 2 electrons in its outer most shell while cl has 1 electron vecancy in its outermost shell). So ca would make bond with 2 cl atoms

A student receives 83.2 points, 44.6 points, 74.4 points, and 52.3 points on each of four tests. Determine the student’s test av
Leya [2.2K]

Answer:

Average = 63.6

Explanation:

Average : The average of the given set of points can be calculated by dividing sum of the total point to the number of points.

Average =\frac{Sum\ of\ points}{Number\  of\ points}

The points that are given in this equation are:

83.2 , 44.6 , 74.4 , 52.3 .

These are 4 in number . So average is

Average =\frac{Sum\ of\ points}{Number\  of\ points}

Average =\frac{83.2+44.6+74.4+52.3}{4}

Average =\frac{254.5}{4}

Average =63.625

Significant digits : It is the number of digits that carry meaningful value to a measurement. The rules for counting number of significant digits are:

1. all non-zero digit are significant

2.Any zero between two non-zero are also significant.(305 = 3 significant digit )

3. Zero before the decimal are non-significant (0.003 = only 1 significant digit)

Zero after decimal are significant (3.00 has 3 significant digit)

4.Zero after non - zero digit is non significant (300 has 1 significant digit).

Significant digits in division :

The answer should have the significant digits that are least in any of number(83.2 , 44.6 , 74.4 , 52.3 )

All have = 3 significant digits.

So least numner of significant digit =3

Answer should have total = 3 significant digits

So,

Average = 63.6
