Water is a relatively good conductor of heat. I said "relatively" because it depends on what you compare it with. To show that it is a bad conductor of heat, you need to compare it with something that is even better conductor of heat (i.e. metal).
What you can do:
Use 2 fresh ice cubes that are similar in size. Put one inside a cup of water in room temperature. Wrap the other one with aluminium foil. Observe and you will see that the one that is wrapped with aluminium foil melts faster.

Give an experiment to show that air a bad conductor of heat?
horrible
How would you show that water is not a good conductor of heat?
A test tube is filled with tap water (about 25oC). An ice block is placed in the test tube and is kept at the bottom of the test tube by means of a wire gauze. Next (without delaying too much since the ice block would melt completely!), the test tube is bent and the upper end of the test tube placed in a Bunsen flame. It is found that the water at the upper end boils before the ice block melts. This shows that water is a poor conductor of heat.
Can a water slide produce thermal energy with friction?
technically yes but if you watch it with a thermal camera it will not show up due to the colder water running over the heat and cooling off the heat spots quite fast
What activities that show radiant energy?
The activity that show radiant energy is by putting a solar light on your environment ..
What is the sankey diagram for a radio?
it is a diagram that show how much heat has come thourth
Do you have any suggested science activity for heat transfer can you provide examples?
To show heat transfer all you need to do is heat up a substance. Like a beaker of water. To show the heat transfer, bring the water to boiling. While doing that measure the temperature of the water to show that the temp is increasing. This is a VERY simple activity. You could also let some ice melt as you take temperature readings, showing that heat was transferred from the air into the water.

Activity to show that liquid do not have definite shape and size?
Pouring water into randomly shaped vessel. Water balloons.
Why methylcinide show exothermic reaction with water?
Because it is its property to release heat when it reacts with water.
What property of the water most likely change after the teacher added the sugar?
Well, if you adding sugar to a beaker of distilled water, then you will find that the water is now a conductor of electricity. You can show this with a conductivity tester.
I you wish to warm 100 kg of water by 20 degrees C for your bath show that the amount of heat is 2000 Calories?
100kg of water by 20c for your bath, show that 8370 kJ
Which processes of the water cycle show heat being added and which ones show heat beign removed?
How the water cycle and heat are related: Adding or subtracting heat makes the water cycle work. If heat is added to ice, it melts. If heat is added to water, it evaporates. Evaporation turns liquid water into a gas called water vapour. As water goes through its cycle, it can be a solid (ice), a liquid (water), or a gas (water vapour). Ice can change to become water or water vapour. Water can change to become ice or water vapour. Water vapour can change to become ice or water. If heat is taken away from water vapour, it condenses. Condensation turns water vapour into a liquid. If heat is taken away from liquid water, it freezes to become ice. The water cycle involves the sun heating the Earth's surface water and resulting in the surface water evaporating. The water vapour rises into the Earth's atmosphere. The water cools and condenses into liquid droplets. The droplets grow until they are heavy and fall to the earth as precipitation (which can be rain, freezing rain or snow).
What is the role of water for acid to show its properties?
As we all know that we should add acid to water not water to acid. Because it can give a lot heat out which can cause saviour burns to our skins and clothes. when the acid evolves a lot of heat it is a strong acid and when small amount of heat evolves it is a weak acid.
What sHow is the water pump is bad on a car?
After running your car for 20 minutes or so ,and there is coolant in the radiator, you will get no heat.
Characteristics of metal are?
Good conductor of heat and electricity.Malleable and ductile.Metals show mettalic lusters.Usually found in solid state but cesium,gallium and mercury exist in liquid state.They are hard and bonded together by metallic bond.
