if you had to explain to someone the difference between heat and temperature, how could you use one of the following to demonstr
Rainbow [258]

Answer:

We associate paper money or points in video games, as molecules that make a heat transfer or an increasin in its temperature.

Explanation:

The meaning of heat is associated with an energy transfer, where for example if we put a spoon in a cup of hot drink, the drink will be transferring heat to the spoon. It is a transfer of energy between two bodies due to a difference between their temperatures.

Temperature is associated with the movement of kinetic energy of the molecules. When the temperature is higher, the kinetic energy is higher, so as more detained they are, temperature will be lower.

If we take paper money as molecules, the greater movement of money explains that we have an increase in temperature (we would be hot), even if we think of video games, for example gambling where as more points we gain, we generate an increase in the movement of "molecules".

When we use paper money to buy something we are doing a heat transfer.

We can associate terms to the Thermodynamic where

Heat = Internal energy + work

For clearance would be

Internal energy = Heat - Work

The money we use less the work we do keeps our internal energy. If in a gambling video game, we earn points over and over again, when withdrawing the prize we perform "heat transfer".

A length of 10 cm equals how many dm? Mark all that apply.
kkurt [141]

Answer:

1 dm

Explanation:

Centimeter and decimeter both are units of length.

Centimeter is represented as "cm" while decimeter is represented as "dm"

centimeter is larger than decimeter. One centimeter have 10 decimeter.

1 cm = 10 dm

So in order to convert cm to dm we will divide the given value by 10.

10 dm × 1 cm/10 cm

1 dm

e. all of the above

Explanation:

An hypothesis is a proposal to solve or answer a new or strange phenomenon that is  not suitably explained by current scientific knowledge. The outcome of an hypothesis is not predetermined. An hypothesis can be termed a scientific hypothesis only when the statements of the hypothesis can be tested also known as the testability of the hypothesis. Hypothesis are normally focused on observations that are unexplained by current scientific theories
