Sunlight bringing thermal energy enters the greenhouse and gets reflected around. However, because of refraction, the light is unable to escape out of the greenhouse. As such, the heat stays inside as well.

What will happen when a gold object is heated?
how do I know
When an object is heated it increases What is this called?
thermal expansion
Can an object being heated be hotter than the source heating it?
Yes, the only way for that to work is if you have the right amount of oxygen, though. Blue fire can get hotter if it's heated by red fire and sand can be heated by lightning, causing it to turn to glass. Without the the right amount of oxygen, the object being heated will only get as hot as its source. Very rarely does the object get hotter than its source.
How heat transfer by conduction?
the particles at the heated end in say a metal rod gain kinetic energy and therefore start to vibrate more. These heated particles then hit other less energetic (hot) particles and then the heat is passed on that way until the whole object is heated up.
Why do materials expand once heated?
This is called thermal expansion. When an object is heated, it's particles move faster. This causes greater separation between the particles and the object expands. The coefficient of thermal expansion describes how much an object will expand per degree with the same applied pressure.
What is a hot house?

How were greenhouses heated before electricity?
the sun Not only were greenhouse heated from the engery produced by the sun but also by heat from paraffin heaters and heated water pipes heated by coal or wood fires.
What is a hothouse?
A hot house is an artificially heated greenhouse for the cultivation of tender plants.
Does the volume of an object change if heated?
The volume of a substance increases when heated
What will happen if the greenhouse effects continues to increase?
people will die
Will a mass of an object increase after heated?
no
What is a building enclosed with glass in which plants are grown in called?
A hot-house, if heated to grow tender exotic plants. Or an unheated greenhouse in summer, or one that is moderately heated to keep it above freezing in winter. It depends on your climate and how tender the plants are.
When you heat up an object does the average kinetic energy of its particles decrease?
No: Upon being heated, the average kinetic energy of the particles that compose the object increases.
