How is heat transfererred when a can of soda is placed in ice or ice-water is it conduction or convection?

Heat is transferred from the Soda to the Ice through conduction, because they are in contact. If they aren't in contact, the heat source will emit its heat energy by convection(if there is another medium, like air, between the objects) and radiation(through Electromagnetic waves).

What are the precautions for the experiment of to show the conduction and convection methods of transmission of heat?
The precautions are -wire gauze should be placed in between the flask and tripod stand while heating process.clamp the flask gently in the retort stand.
What are the three types if heat transfer?
The three most common types of heat transfer are convection, radiation, and conduction. Convection is the movement of heat through a liquid. Radiation is the movement of heat from a distance like the sun warms the earth and a fire warms things that are near. Conduction is the transfer of heat through touch like when you touch a hot pan, stove, etc.
What is it when energy from hot cocoa melts a marshmallow placed in it?
This is convection. Convection is the effect you get when hotter parts expand and have lower density than cooler parts. What you describe is "melting", with the temperature of the surrounding liquid being higher than the temperature of the marshmallow. So, heat flows from the hotter region to the cooler by conduction and eventually the temperature reaches the melting point.I'd suggest re-arranging that.Conduction transfers the cocoa's heat into the marshmallow, cooling the liquid in doing so.Convection helps to maintain the process by replacing the cooled cocoa with hot.When you place any chocolate in any fluid at a higher temperature than the melting point of chocolate, the chocolate will melt. Likea lump of ice in warm water. Convection playsno role at all- if you prevent convection by packing the fluid with small pebbles etc, the marshmellow will still melt. The heat is transferred by conduction, not convection.
A heating element being placed in one end of an aquarium can heat the whole aquarium because of heat transfer by?
conduction
Why are heaters best placed on the floor of the room?
Heaters are placed on the floor because of convection currents. Convection currents are the circular motion of air currents, caused by the simple fact that cool air is heavier than warm air. Thence, warm air rises. Heaters are placed on the floor to get the heat to people before the air cools down and begins to sink.

When Ice melts in iceboxes because .?
through the insulted walls, door when it is open,and warm food placed in the refrigerator
Why does a plate become hot when hot food is placed on it?
"conduction"
Why does the water boil in container when the utensil is placed on a flame?
due to conduction
When a metal spoon with temperature of 20 is placed into a cup of water with a temperature of 90 the spoon will heat up this is an example of?
Conduction
Is heating vents placed on the floor at home convection?
yes
What direction will heat energy move when placed with a cold object?
convection
Where should a heater in a water tank be placed to efficiently warm the water?
It will be most efficient if placed at or near the bottom so that convection will move the heated water upwards, warming the water above it as it rises and allowing the colder water to sink downwards towards the coils. If the heating element were placed higher up, the water below would have to warm almost exclusively by conduction which would take much longer.
Why paper placed on the top of a candle burns first than one placed on the side?
Because the flame travel upward, anything in the path of heat convection burn first. For information and fun fact, heat travel in 3 mode, conduction, convection and radiation. Thermal convection is heat travel with the medium, in this case, air mass. The heat from candle cause the air to expand and get lighter thus the air float up to the top side. Heat is then convected mostly to the top side. If the experiment would be repeated in space, there will be no different if the paper on the top or on the side would burn first.
