At which volume of base added was all the acid neutralized?

there is an ice cream shop 6 blocks north of your hotel. how many minutes will it take to walk there and back

Allushta [10]

Answer:

This question is incomplete

Explanation:

This question is incomplete.

However, when all the required data are available, you can use the formula/steps below

Average speed/velocity (m/s) = distance (in metres) ÷ time (in seconds)

Time (in secs) = distance ÷ average speed/velocity

Kindly note that "blocks" is not a standard unit for distance measurement in science, hence the distance (since its a walking distance) must be in metres (or converted to metres if not in metres).

The distance in the formula is the distance from the hotel to the ice cream shop while the average speed is the distance covered per time as s/he walks to the ice cream shop and back. Hence, the answer gotten from the formula above will have to be multiplied by 2 (in order to get the time taken to walk to the ice cream shop and back) because the formula will only provide answer to one trip (time taken to walk to the shop).

After the multiplication mentioned above, the time in seconds should be converted to minutes by dividing the answer in seconds by 60

What is the change in internal energy (ΔΕ) of a system when 5 kJ of work is done on the system while it releases 13 kJ of energy

meriva

The change in internal energy (ΔΕ) of a system : -8 kJ

<h3>Further explanation </h3>

The laws of thermodynamics 1 state that: energy can be changed but cannot be destroyed or created

The equation is:

$\tt \Delta U=Q+W$

Energy owned by the system is expressed as internal energy (U)

This internal energy can change if it absorbs heat Q (U> 0), or releases heat (U <0). Or the internal energy can change if the system does work or accepts work (W)

The sign rules for heat and work are set as follows:

• The system receives heat, Q +

• The system releases heat, Q -

• The system does work, W -

• the system accepts work, W +

5 kJ of work is done on the system : W = +5 kJ

releases 13 kJ of energy to the surroundings : Q = -13 kJ

$\tt \Delta E=-13+5=-8~kJ$

A student observes that water in a pot on a burner becomes hotter explain how energy is conserved in the situation

Daniel [21]

The water in the pot becomes hotter as a result of heat transfer.

<em>Energy can be transferred from a region to another , but there will still the same overall amount of energy</em> ( energy conservation)

When a pot containing water is placed on the stove and heat is applied with the burner, there is a flow of heat from the burner to the water.

Heat will be transferred from the burner to the pot, then there will be transferred of heat from the pot to the water, the molecules there in the water will be energized as a result of the heat transfer until the boiling point is reached.

Energy transfer can take place in three form, this could be conduction, radiation or convention.

Convention which is a cyclical process is the one that occurs in fluids only so as a result of convection , the water at the bottom will be heated and the molecules start moving and it will rise till it get to the water at the top of the pot.

<em>Therefore, the water is heated as a result of heat transfer.</em>
