Yes because your computer was built to last a certain heat from the proccesor. The more Ghz, the more heat. Try to get a PC cooler so you don't need to install a whole new cooler.
Yes you will as CPU manufactures prefer if you use there CPU cooler as the cooler has been designed for the thermal rating of the CPU.

The first suspect would be the CPU cooler. You need to open your laptop and clean and from dust including parts of the cooler. Most likely the cooler has to be replaced. In some cases it's possible to repair including relubricating. Also make sure that all other fans if you have more than one are working properly, if not repeat the procedure for others too.

A laptop if you want a complete computer that you can carry around (there is a CPU in a laptop)A CPU if you have a computer and want to upgrade or replace the "Central Processing Unit" which is the most expensive and complicated component.

The CPU of a laptop is the central processing unit that is basically the heart of your laptop and can perform various applications on how powerful it can be, it is a chip on your laptop motherboard that is removable or sometimes integrated. EX. a 2ghz is much weaker compared to a 4ghz cpu. Without the CPU your laptop is a piece of junk because it will not turn on. A CPU can be optimized for basic tasks such as word documents to extreme gaming. Personally fo you are looking forward to buying a computer go with a higher end CPU as long as it fits your budget because a low end CPU will frustrate you especially if you are a gamer. You will know if you found a CPU is it says Intel or AMD.

You can probably download phone apps to a standard laptop, but they won't be able to run because the laptop CPU and OS are incompatible with the smartphone CPU and OS that the apps were coded for. But if you had them on the laptop and then downloaded them from the laptop to the smartphone, they would run on the smartphone.
Both the processor, which allows the computer to do tasks, the better that is, the faster your computer can work the RAM which stores the things for the processor to process, the more you have the better. AND the hard drive, the faster this is, the faster the processor can grab information off it.
For the most part no just about every single laptop on the market has an integrated CPU so switching it for a faster one is not happening. When you need a more powerful laptop you should just a newer one. newer laptops are just as fast as some desktops and the entire system costs about $1000 for a nice one. If its speed you want buy some ram that you can change out
If you are saying to take it out of a laptop and put it in a desktop computer, then no. Laptop processors (as far as I have seen) are soldered into the motherboard, and designed only for motherboards for laptop sizes. Which in that case, it isn't possible to use a laptop processor in a desktop PC.
