There are two possible ways to heat a substance in the lab. If you are heating something in a large container, you should put it on a hot plate, which is a device which converts electrical energy into thermal energy. If you are using a test tube, then you should heat it over a bunson burner. Grab hold of the test tube using beaker tongs, and set the bottom of the tube a little above the flame. Point the tube away from yourself and others, as the substance may shoot out without warning. Once done, set it back on the rack.

What do you expect to learn from this lab activity?
"This" means a specific lab project. Without knowing what activity, there is no way anyone can answer the question.
Why is eating or drinking not allowed in the science lab?
This has to be the most ridiculous question EVER.

Why the specific heat capacity of a substance depends upon phase?
The capacity for an object to be heated and retain heat is determined by its phase because of the way the different phases of matter move. The more freely the molecules are able to move around (like in a gas), the more likely the excited (or warmed up) molecules will leave the group, causing the heat to dispress more quickly.
What is the major way that heat is transferred in the troposphere?
convectionQ: What is the major way that heat is transferred into the troposphere?A: Convection
What is the proper way to heat a liquid in a test tube?
the proper way to heat a liquid in a test tube is by putting it in open flame.
Suppose that 28 g of each of the following substances is initially at 27.0circ C What is the final temperature of each substance upon absorbing 2.45 kJ of heat?
To find the final temperature of each substance, you need to calculate the specific heat capacity of each substance. Once you have the specific heat capacity, you can use the formula Q = mcΔT to find the final temperature. Substituting the given values into the formula will give you the final temperature of each substance.
What should be used to remove heated to heated objects?
When a substance is heated up, it emit heat radiation. In such way substance keep on losing heat energy. Thus a way that increase heat losing can lower heat of substance. Water can used as heat absorber.
Thermal energy is another way of saying what?
Thermal energy is another way of saying heat energy. It refers to the energy that comes from the movement of particles within a substance.
Is combustion one way to release potential energy in a substance?
Yes, combustion is a process that releases potential energy stored in a substance in the form of heat and light. During combustion, a substance reacts with oxygen to produce energy in the form of heat and chemical energy.
Why cant heat travel from the grill to toast by convention?
Conduction is the process of heat diffusing through a substance that conducts heat. The less conductive the substance is (like glass, air, or an oven glove), the slower the conduction is. Convection is the movement of heat that occurs when a mass of hot substance physically moves to another location. Both of these mechanisms depend on the presence of a material substance to move heat from place to place, and the efficiency of the mechanism depends on the characteristics of the substance. Radiation is the movement of heat in the form of electromagnetic radiation. It doesn't require any substance in the intervening space to transfer the heat; in fact, it is most efficient when there is NOTHING in the way. That's how heat reaches us from the sun.
How could you determine the specific heat of a sample of a solid substance that does not react with water?
One way to determine the specific heat of a solid substance that does not react with water is by using the method of calorimetry. This involves measuring the temperature change of the substance when it is heated or cooled, and using the formula q = mcΔT to calculate its specific heat capacity, where q is the heat added or lost, m is the mass of the substance, c is the specific heat capacity, and ΔT is the temperature change.
Is a burn a allergic reaction to heat?
No. An allergic reaction is the body's way of responding to a foreign substance, or an antigen.
Is there a way to remove heat from a substance how?
get shaving cream and pour some in
How can you add heat to a substance without raising its temperature?
One way to add heat to a substance without raising its temperature is by changing its state of matter. This process, known as phase change, involves adding heat energy to a substance to change it from a solid to a liquid or from a liquid to a gas. During this phase change, the temperature of the substance remains constant until the phase change is complete.
What is the proper way of using devices to produce heat?
use low wattage light bulbs
Does temperature measure heat energy?
Temperature is a measure of the average kinetic energy of the particles in a substance, not the total heat energy. Heat energy is the total energy associated with the movement of particles in a substance. Temperature is one way to quantify the amount of heat energy present in a system, but it is not the same as measuring the total heat energy.
