Which requires more energy, making soup or making toast? Explain.

➪ Making toast requires more energy according to my knowledge because soup is liquid and in liquids the particles move freely and allows heat to transfer more quickly in it. Thus, Soup is made quicker and hence requires less energy whereas a toast (piece of bread) is solid and particles are tightly packed thus they need more energy to get cooked.

What are advantages of double glazed windows?

➪ Double glazed windows are air tight and are sealed properly. They cannot be broken easily which makes it more safe. Double glazed windows reduce the amount of moisture on your window panes, as the airtight seal prevents the condensation from building up. And no condensation means the house will be warmer.

When poor people are forced to sleep outdoors in cold weather, they sometimes use newspapers for blankets. What good is this? Why?

➪ They use newspapers because they have very minute holes in it which have air trapped and that trapped air is bad conductor of heat which does not allow the heat of body to flow outside and keeps them warm.

Why are loose fitting clothes more comfortable than the tight fitting clothes in hot climates?

➪ Loose-fitting clothes allow air to pass through and allows the heat of body to flow out which makes us feel cool whereas tight fitting clothes are touched with skin and does not allow the air to pass through the pores. Thus, making loose clothes more comfortable in hot climates.

How does a thermos flask keep food hot?

➪ A thermos flask does not have any pores or holes in the outer surfacs or inner surface which creates a vaccum inside the flask and does not allow heat to escape. Hence, keeping the food hot for very long time.

Suppose a tank filled with water has a liquid column with a height of 10 meters. If the area is 2 square meters (2 m²), what's t

Vesna [10]

Answer:

196000 N

Explanation:

The following data were obtained from the question:

Height (h) = 10 m

Area (A) = 2 m²

Force (F) =.?

Next, we shall determine the pressure in the tank.

This can be obtained as follow:

P = dgh

Where

P is the pressure.

d is the density of the liquid.

g is acceleration due to gravity

h is the height.

Height (h) = 10 m

Density (d) of water = 1000 kg/m³

Acceleration due to gravity (g) = 9.8 m/s²

Pressure (P) =...?

P = dgh

P = 1000 × 9.8 × 10

P = 98000 N/m²

Therefore, the pressure acting on the tank is 98000 N/m²

Finally, we shall determine the force of gravity acting on the column of water as follow:

Area (A) = 2 m²

Pressure (P) = 98000 N/m²

Force (F) =.?

Pressure (P) = Force (F) /Area (A)

P = F /A

98000 = F/ 2

Cross multiply

F = 98000 × 2

F = 196000 N

Therefore, the force of gravity acting on the column of water is 196000 N

The average depth of Indian Ocean is about 3000m.Calculate the fractional compression. ▲v/v, of water at the bottom of the ocean

Klio2033 [76]

Answer:

∴ fractional compression = 1.34 × 10⁻²

Explanation:

given,

depth of Indian ocean = 3000 m

Bulk modulus of the water = 2.2 x 10⁹ N/m²

We know,

P = P₀ + ρgh

P₀ is the atmospheric pressure

P₀ = 10⁵ N/m²

ρ is the density of the water, 1000 Kg/m³

P = 10⁵ + 1000 × 9.8 × 3000 = 2.94 × 10⁷ N/m²

using formula,

B = P/{-∆V/V}

B is bulk modulus and { -∆V/V} is the fractional compression

$\dfrac{-\Delta V}{V} = \dfrac{2.94 \times 10^7}{2.2 \times 10^9}$

$\dfrac{-\Delta V}{V} =1.34 \times 10^{-2}$

∴ fractional compression = 1.34 × 10⁻²
