In terms of heat conservation how can heat be lost from a hot test tube containing wax?

Heat is transferred by three methods; Convection, conduction or radiation.
If the test tube is touching anything (such as the stand or a table) then heat can be lost through conduction; the hot test tube transfers heat to the stand. You can reduce this heat loss by using a material such as wood that does not conduct heat well.
The air around the test tube will be heated, and the hot air rises away, allowing cold air to flow around the test tube. The new cold air becomes heated, and rises away and.... This is called convection.
Even in a vacuum, the heat of the test tube will be lost through radiation, as the heat of the test tube is transferred to nearby objects. If you put your hand near the test tube, you can feel the heat even without touching it. This is how the heat from the Sun reaches the Earth, even though we're not touching the sun and the 93 million miles of space between us and it is a pretty good vacuum.

How is calorimetry related to the law of conservation of energy?
The Law of Conservation of Energy states that energy is neither created nor destroyed but remains constant in a given system. Therefore, wouldn't calorimetry make use of it because the energy gained/lost by the water would cancel out the energy lost/gained by the substance and result in no change overall?

How would you use the word conservation of mass in a sentence?
The Law of Conservation of Mass means that chemical reaction equations must be balanced, otherwise you have lost or gained matter out of nowhere.
What does conservation of mass mean in science term?
That mass can not be gained nor lost - except in a nuclear reaction where it can be exchanged for energy.
What law states that the mass can not be lost or gained in a chemical reaction?
The law of conservation of mass states that in a chemical reaction the mass of the reactants must equal the mass of the product.
How does the of the conservative of mass apply to chemical reactions?
The law of conservation of mass states that in a close container, when a chemical reaction occurs, no mass will be lost.
If the efficiency of a machine is always less than 1 why is the principal of conservation of energy still obeyed?
Conservation of energy is not violated because some of the energy is always lost as heat (due to friction).
What is energy conservation and why should citizens conserve energy?
Energy conservation is that energy cannot be created or destroyed it can be transferred or transformed. We conserve energy no matter what we do. What we are really being told is to conserve usable energy which is energy not in the form of heat. We are told this to avoid the heat death of the universe this is when all the usable energy is lost due to heat.
The law of conservation of energy states that energy can be created or destroyed as long as it is later converted to a more common form?
No, the Law of Conservation of Energy (a.k.a. First Law of Thermodynamics) states that energy CAN NOT be created or destroyed. Converting energy to a less valuable form is related to the Second Law of Thermodynamics.

Can mass be lost?
Mass can not be lost. According to the Law of Conservation of Mass, matter can not be created or destroyed.

What law of conservation says atoms are neither lost nor gained during a chemical reaction?
Law of Conservation of Matter.
How does perpetual motion machine fits the principal of conservation of energy?
Perpetual motion would only fit the principle of the conservation of energy if it was a machine that moved that did not have any friction or produce any sound or produce any form of heat or energy that could be lost in any way. Since no such machine is possible to create, as far as we know, perpetual motion is declared an impossibility and does NOT fit the principle of the conservation of energy. Energy will undoubtedly be lost somewhere in a moving system.
Elements can be lost or gain in chemical reaction?
Elements cannot be lost/gained: this is the law of mass conservation.
What happens to the remaining energy that is not used for life processes or lost as heat?
what happened to the energy that is not stored in your body
Energy is lost from a reaction in a form of what?
energy of a reaction will be lost in the form of heat.
What law states that energy is neither lost nor gained?
That would be the law of conservation of mass, conservation of matter.
