Answer:

THE NEW PRESSURE OF THE HELIUM GAS IS 124kPa AFTER THE VOLUME WAS INCREASED FROM 2.48 L TO 2.98 L

Explanation:

Using Boyle's law which states that at constant temperature, the pressure of a given gas is inversely proportional to the volume occupied by the gas.

Mathematically,

P1 V1 = P2 V2

P1 = 150 kPa = 150 * 10^3 Pa

V1 = 2.48 L

V2 = 2.98 L

P2 = ?

Rearranging the formula making P2 the subject of the equation, we obtain;

P2 = P1 V1 / V2

P2 = 150 * 10^3 * 2.48 / 2.98

P2 = 372 * 10 ^3 / 2.98

P2 = 124.83 * 10^3 Pa or 124.8kPa

In other words, the new pressure of the helium gas after its volume was increased from 2.48 L to 2.98 L is 124.8kPa.

What are the conditions for evaporation?
SashulF [63]

Answer:

For evaporation you need a warm, preferably humid temperature. The rate of evaporation increases with an increase in temperature. A windy climate is best, as wind helps to remove the evaporated water vapour, and therefore creating a better scope for evaporation to continue. The speed of wind is important for evaporation because the wind pulls in dry air, increasing the rate of evaporation.

Short Answer- Hot and humid temperature, lots of wind speed.

It's actually Science but I didn't find it.

Answer:

Forces acting on an object may be balanced or unbalanced. When the forces  acting on an object have <u>equal</u> strength and act in opposite directions, they  are <u>balanced</u>. These forces cancel out one another, and the <u>motion</u> of the  object does not <u>change</u>.  When the forces acting on an object are <u>unbalanced</u>, they do not cancel out  one another. An unbalanced force acting on an object results in the object’s  motion <u>changing</u>. The object may change its <u>speed</u> (speed up or slow down), or it may change its <u>direction</u>.  <u>Friction</u> is a force that resists the motion or the tendency toward motion  between two objects in contact with each other.  <u>Gravity</u> is a force that pulls objects toward one another. For example, Earth  pulls all objects toward it.
