Write like this using ternary operator.

$key_1_value = get_post_meta(get_the_ID(),'hot',true);
// Check if the custom field has a value.
<h2><a  <?php echo (! empty( $key_1_value )) ? 'class="hottitle"' : '';  ?> title="<?php echo get_the_title_attribute(); ?>" href="<?php echo get_the_permalink() ?>"><?php echo get_the_title(); ?></a></h2>

Refer this link for more information https://developer.wordpress.org/reference/functions/get_post_meta/

It's either <?= or <?php or (if for some reason you use short tags) <?.That's it.
