Which factors in an ecosystem provide food (plants, fish, and livestock) or inhibit agriculture (insects)?

When a kettle is placed on the stove and water begins to boil, the hotter water at the bottom begins to rise and the

My name is Ann [436]

Answer:

The cooler water is denser

Explanation:

Convection drives the boiling of water placed on a stove in a kettle.

During convection, heat is circulated by density differences in portions of a fluid.

Convection is a form of heat transfer in fluids especially gas and liquid.

In boiling water, the heat is supplied to the base of the stove.
The water at the bottom on heat becomes lighter as the molecules gain more kinetic energy.
The colder part of the water on top sinks to replace the less dense on below.
This exchange sets up convection cells in the kettle.

The specific heat of copper metal is 0. 385 J/(g °C). How much energy must be added to a 35. 0-gram sample of copper to change t

Rus_ich [418]

The amount of heat required for changing the temperature of copper has been 606 J. Thus, option B is correct.

Specific heat has been defined as the amount of heat required to raise the temperature of 1 gram of substance by 1 degree Celsius.

The heat required to raise the temperature has been expressed as:

$\rm Heat=mass\;\times\;specific\;heat\;\times\;Change\;in\;temperature$
