The sun has more gravity than the other planets in our solar system because the sun is
a) hotter.
b) more massive.
c) made of plasma.
d) undergoing fusion.

The Sun has more gravity than the other planets in our solar system because the Sun is more massive (answer B)

Gravity is a force that arises because of the attraction between objects with mass.

The magnitude of this attraction is proportional to the mass of the object.

The greater the mass of the object, the greater the gravitational force

Relationships can both be stated in

Newton's Gravity Law:

with F = gravitational force,

G = 6.67 × 10−11, gravitational constant,

m1,m2 = mass of object,

r = distance between two objects.

If we look at the solar gravitational acceleration data of 274 m/s², it is 28 times greater than the Earth's gravitational acceleration of 9.8 m/s², so this shows the solar attraction of other planets in their respective orbits in the solar system

So the best answer is B. more massive

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
