Show posts from specific category on WordPress page

I’m trying to create a page that will display posts from a specific category.

I have installed the plugin: https://wordpress.org/plugins/insert-php/

Here is the code I’m using:

<?php
query_posts('cat=2');
while (have_posts()) : the_post();
the_content();
endwhile;
?>

This code works perfectly for me but the problem is that it does not display the title of the post. It directly shows the excerpt.

Can someone please modify the code and make it show the post title in h1 format, and also display date, author, and category?

Thank you in advance.
