This is my code
\documentclass[12pt,a4paper]{book}
\renewcommand{\baselinestretch}{1.5}
\begin{document}
\include{Chapter1}
\end{document}
I have please a question:
I would change the line spacing (1.5 --> 1.0) of a page inside the document and not the entire document and the size of the words, how can I do please?
You can use \setstretch{}. If you want to only affect a certain content you can use it with a group.
You can also apply any size changing switches such as \small or \tiny inside the {} group as well.
\documentclass[12pt,a4paper]{book}
\usepackage{xcolor}
\usepackage{lipsum}
\usepackage{setspace}
\renewcommand{\baselinestretch}{1.5}
\begin{document}
\lipsum[1]
{\setstretch{1.0}\color{blue}
\lipsum[2]
}
\lipsum[3]
\end{document}
} (\lipsum adds a \par at its end). Using \linespread{1.5} (or some command of setspace) is better than redefining \baselinestretch.
{}, or within \begingroup, \endgroup pair. If that does not help you achieve the desired results you should post a separate question. Also, please note that you should use the full username with the @ syntax. I was only notified of this as it was a comment to an answer of mine.

minipage with TeXLive 2021. I suggest you post a new question and include a fully compilable MWE including \documentclass and the appropriate packages that reproduces the problem. Also, include a \listfiles before \begin{document}. This will output the versions of the pacakges and including that in your question will help to determine if some of your packages are not up to date.

Alternatively, the following solution is a bit cleaner:
\documentclass[12pt,a4paper]{book}
\usepackage{lipsum}
\usepackage{setspace}
\begin{document}
\onehalfspacing % Set line spacing to 1.5
\lipsum[1]
\singlespacing % Reset line spacing to 1 from here on
\lipsum[2]
\onehalfspacing % Reset line spacing to 1.5 from here on
\lipsum[3]
\end{document}
For other values, you can use e.g. \setstretch{1.125} instead of \singlespacing and \onehalfspacing.
The advantage of this method is that you don't need a closing statement, such as end{} or a curly bracket.
setspace.
Other line spacing values that lie in between onehalf, single and double can also be achieved with:
\usepackage{setspace}
\begin{spacing}{1.125}
…
\end{spacing}
Instead of redefining \baselinestretch, you can set a new value to \linespread and apply the changes with \selectfont:
\documentclass{article}
\begin{document}
\linespread{1.0}\selectfont
Lorem ipsum dolor sit amet, consectetur adipisici elit, sed eiusmod tempor incidunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquid ex ea commodi consequat.
\linespread{2.5}\selectfont
Lorem ipsum dolor sit amet, consectetur adipisici elit, sed eiusmod tempor incidunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquid ex ea commodi consequat.
\linespread{1.5}\selectfont
Lorem ipsum dolor sit amet, consectetur adipisici elit, sed eiusmod tempor incidunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquid ex ea commodi consequat.
\end{document}
A friendly reminder for everyone using the memoir class that it provides its own mechanisms for line spacing:
\begin{Spacing}{0.9}
tightly spaced text
\end{Spacing}
There are also SingleSpace, OnehalfSpace and DoubleSpace environments;
starred versions of those that do not automatically add \vskip\baselineskip at the end;
various crutches to fine-tune everything; etc.
Take a look at p. 51 of texdoc memoir.
