That's more than 275 million stars per day in the observable universe. Stars keep themselves fueled. They fuse elements together to make new elements.Once the star runs out of hydrogen, the helium atoms fuse together to make carbon.
Bromine has stronger inter molecular force than Fluorine.
<h3> Inter molecular forces and relationship with physical states of matter</h3>
The intermolecular forces of a substance tells the physical state of that substance , We can therefore say that the Solid, liquid and gas states of substances depends on the intermolecular forces surrounding them.
- For solids,the inte molecular forces will be so strong as they draw the molecules together giving them a compact structure.
- For liquids, the the inter molecular forces will be just strong enough to keep the molecules together in a confined space.
- For gases, the the inter molecular forces are weakest as the molecules move about.
We can then conclude that At stp, fluorine is a gas and bromine is a liquid because, compared to fluorine, bromine has a stronger intermoleclar force.

The statement that describes the change in energy as one slide from the top is the decrease in the gravitational potential energy is equal to the increase in kinetic energy.
<h3>What is Kinetic energy?</h3>
This is known to be a kind of energy that is seen in an object or a particle due to its motion.
Based on the above scenario, As the block goes or slides down, its potential energy is known to lower or decreases and its velocity is said to increases and therefore, it's kinetic energy is increasing.
See options below
O The decrease in the gravitational potential energy is equal to the increase in kinetic energy.
O The sum of the kinetic energy and the gravitational potential energy changes by an amount equal to the energy dissipated by friction.
The gravitational potential energy and the kinetic energy must both decrease.
The gravitational potential energy decreases, and the kinetic energy is constant.
