5 0

To lengthen a pattern piece for sewing a garment, cut the paper pattern where indicated. It will normally state "lengthen or shorten here". Open the cut to the desired amount you need to add to your pattern. Place a piece of tissue paper underneath and tape in place. Keep the grain line correct and even. Make sure you do this to all your pattern pieces used for the garment.

A bowl containing 70 grams of water, is heated from 10 °C to 90 °C. The specific heat of

storchak [24]

Answer:

23430.4 J.

Explanation:

From the question given above, the following data were obtained:

Mass (M) = 70 g

Initial temperature (T₁) = 10 °C

Final temperature (T₂) = 90 °C

Specific heat capacity (C) = 4.184 J/gºC

Heat (Q) required =?

Next, we shall determine the change in the temperature of water. This can be obtained as follow:

Initial temperature (T₁) = 10 °C

Final temperature (T₂) = 90 °C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = 90 – 10

ΔT = 80 °C

Finally, we shall determine the heat energy required to heat up the water. This can be obtained as follow:

Mass (M) = 70 g

Change in temperature (ΔT) = 80 °C

Specific heat capacity (C) = 4.184 J/gºC

Heat (Q) required =?

Q = MCΔT

Q = 70 × 4.184 × 80

Q = 23430.4 J

Therefore, 23430.4 J of heat energy is required to heat up the water.

You have a ball with a density of 1.3 g/mL and a mass of 8.5 g. what is the volume of the ball

RoseWind [281]

Answer:

The answer is

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = \frac{mass}{density} \\$

From the question

mass of ball = 8.5 g

density = 1.3 g/mL

It's volume is

$volume = \frac{8.5}{1.3} \\ = 6.538461...$

We have the final answer as

Hope this helps you

How would you find 8m of carbon chloride using 87.9g carbon chloride

vaieri [72.5K]

Answer:

Explanation:

I want to believe that your question is how to find an 8M carbon chloride solution using the given mass of the compound.

The problem clearly identifies with concentration of a substance. Molarity is one of the ways of expressing concentration. It is the amount of solute of a substance per volume of solution.

Molarity = $\frac{number of moles of solute}{Volume of solution}$
