1.08 atm is the pressure for a certain tire in atmosphere.
<u>Explanation:</u>
One kilo pascal (1 kPa) corresponds to 1000 pascal. Another common unit used for pressure is atmosphere (symbolised as ‘atm’). 1 atm refers the standard atmospheric pressures and corresponds to 760 mm Hg and 101.3 kPa. Atmospheric pressures are commonly referred as square inches (psi)/ pounds.
Given:
The air pressure for a certain tire = 109 kPa
We need to find pressure in atmospheres
So, we know,
1 atm = 101.3 kPa
Hence,
1.08 atm is the pressure for a certain tire in atmosphere.
Putting solar panels on houses is a great idea, for it provides a renewable source of energy and heat, which is the sun. It will help prevent pollution and the mass-use of non-renewable resources, such as fossil fuels, which are used and burned for energy.
Although, having solar panels, there will be some downsides. For example, solar panels can only receive energy during time where there is light from the sun, which is daylight. therefore, the solar panels will not and cannot be able to collect energy from the sun during night time. although, depending on the solar panels, some can store energy, from the sun, that can be used at night time, like as if you're charging a battery with energy from the sun for later use. one big problem is that, solar panels are not cheap and rather quite expensive, which not all homes and families can afford. although, through time, solar panels will get cheaper.
but, all in all, I believe that solar panels give a great contribution to Earth, thus I agree to the use of solar panels.

Explanation:
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
