 <content:encoded>&lt;div class='rss_texte'&gt;&lt;p&gt;Is there heat transfer between two bodies with different temperatures when they are put in contact?&lt;/p&gt;&lt;/div&gt;
		&lt;hr /&gt;
		&lt;div &lt;div class='rss_ps'&gt;&lt;p&gt;Yes, there is. Heat transfer occurs when systems with different temperatures are in contact and it always flows from the hotter body to the cooler body. This type of heat transfer is called &lt;b&gt;conduction&lt;/b&gt;.&lt;/p&gt;&lt;/div&gt;

 <content:encoded>&lt;div class='rss_texte'&gt;&lt;p&gt;How is heat transferred in the air?&lt;/p&gt;&lt;/div&gt;
		&lt;hr /&gt;
		&lt;div &lt;div class='rss_ps'&gt;&lt;p&gt;&lt;b&gt;Heat is transferred in a fluid (liquids or gases) by convection, which involves the movement of matter. This means that higher temperature air moves from one point to another until the system reaches the thermal equilibrium&lt;/b&gt;.&lt;/p&gt;&lt;/div&gt;
