if the radius of the capillary tube is doubled, what changes will take place in the hieght of rise of liquid with capacity tube
tangare [24]

Explanation:

The height of the rise of liquid with capillary tube is given by the formula as follows :

h=\dfrac{2S\cos\theta}{r\rho g}

Where

r is radius

It is clear that the height of the rise of liquid is inversely proportional to the radius of the capillary tube.

If the radius of the capillary tube is doubled, it means the height of rise of liquid with capillary tube become half.

A graduated cylinder contains 63.0 mL of water. A piece of gold, which has a density of 19.3 g/ cm3, is added to the water and t
icang [17]

Answer:

29.0 g

Explanation:

The mass of the piece of gold is given by:

m = dV

where

m is the mass

d is the density

V is the volume of the piece of gold

The density of gold is

d = 19.3 g/cm^3

while the volume of the sample is equal to the volume of displaced water, so

V = 64.5 mL - 63.0 mL = 1.5 mL

And since

1 mL = 1 cm^3

the volume is

V = 1.5 cm^3

So the mass of the piece of gold is:

m = (19.3 g/cm^3)(1.5 cm^3)=29.0 g

A 0.050 kg metal bolt is heated to an unknown initial temperature. It is then dropped into calorimeter containing 0.15 kg of wat
Pachacha [2.7K]

The initial temperature of the metal bolt is 80.8 °C

We'll begin by calculating the heat absorbed by the water.

  • Mass of water (M) = 0.15 Kg
  • Initial temperature (T₁) = 21 °C
  • Final temperature (T₂) = 25 °C
  • Change in temperature (ΔT)  = T₂ – T₁ = 25 – 21 = 4 °C
  • Specific heat capacity of water (C) = 4184 J/KgºC
  • Heat absorbed (Q) =?

Q = MCΔT

Q = 0.15 × 4184 × 4

Q = 2510.4 J

Finally, we shall determine the initial temperature of the metal bolt.

  • Heat absorbed by water = 2510.4 J
  • Heat released by metal (Q) = –2510.4 J
  • Mass of metal (M) = 0.050 Kg
  • Final temperature (T₂) = 25 °C
  • Specific heat capacity of metal (C) = 899 J/Kg°C
  • Initial temperature (T₁) =?

Q = MC(T₂ – T₁)

–2510.4 = 0.050 × 899 (25 – T₁)

–2510.4 = 44.95 (25 – T₁)

Clear bracket

–2510.4 = 1123.75 – 44.95T₁

Collect like terms

–2510.4 – 1123.75 = –44.95T₁

–3634.15 = –44.95T₁

Divide both side by –44.95

T₁ = –3634.15 / –44.95

T₁ = 80.8 °C

Thus, the initial temperature of the metal is 80.8 °C.
