because the object needs also to heat up
It takes longer to cool off, but mostly depending on the temperature.
The more water in the kettle, the longer it will take to reach boiling point. This is why it is wasteful in energy to boil a full kettle if you only want to brew a small cup of tea.
Because there is more water in a bucket than in a cup, and more energy has to be put into the bucket of water than the little cup of water to bring them to the same temperature.
The boiling point is increased after adding impurities to water.
A small object has a larger surface area (in proportion to its weight) than a larger one. Therefore, a small object, like a small drop of water, will fall slower - it has more air resistance (again, in proportion to its weight). However, it will not float indefinitely; it will simply take longer to get to the ground.
sand will because the molecules of sand are closer together, which makes heat get to the whole object faster, unlike water in which the molecules are spread apart, so it will take longer for all of the heat to get the whole liquid. (i did an experemint in my class, which proves my answer.)
Water takes longer to heat up and to cool down then it does for land.
yes. the more water the longer it would take for the heating element to heat the water. the less water, the less time it would take to heat.
It takes longer to cool off, but mostly depending on the temperature.
Assuming the object is hotter than the water, then heat will naturally flow from the object to the water - no need to take any special measures.
Because when you are cooking sauce it's thicker then water so it takes longer to heat.

Because the specific heat of water is very high. In fact, water has about 1400 times more heat carrying capacity than air.
Water absorbs and conducts radiation better. ex. electricity is a form of radiation this is false because water will take longer to absorb heat than soil but when the source of heat is gone the water will insulate more heat than the soil, therefore the water will keep heat longer than soil but the soil will heat up faster.
Sort of. If carbon has a lower specific heat than water, the more percentage of the water is carbon, the easier it will heat up. Otherwise, it will take longer.
When heat is transferred from one object to another, the thermal energy distributes to have the temperature even throughout the entire object. When there is more material, as you said, as it heats up in one place, the more material, the more the heat has to distribute and the longer it will take to heat up.
Water heats and cools slower than land. It is because the specific heat is the amount of heat that it takes to be raised to a certain temperature. If the heat is higher it would take longer to heat and cool. That is my interpretation anyways.
