Answer:

Q=93.3kJ

Explanation:

Hello,

In this case, by knowing that the heat due to a change of temperature is given by:

Q=mCp\Delta T

Whereas Q accounts for the heat, m for the mass, Cp the heat capacity and ΔT for the change in temperature. In such a way the required heat results:

Q=24.7kg*236\frac{J}{kg^oC}*(30.0-14.0)^oC*\frac{1kJ}{1000J} \\Q=93.3kJ

Best regards.

What is the mass of a 10.0 ml sample of urine with a specific gravity of 1.04?
bija089 [108]
The formula of specific gravity is:

Specific gravity = \frac{density of an object}{density of water}

To get this, you can derive a formula for mass. If you transpose the density of water to the other side of the equation (by specific gravity) you will multiply it with specific gravity. Now the density of water is 1 g/mL so you will retain the value of the specific gravity. That will just leave you with this formula:

Specific gravity = density of an object

Density of an object can be computed using the formula:

Density = mass/volume now you can fuse the two formulas to get this:

Specific gravity = mass/volume

From there we can derive the formula for mass by transposing volume to the other side of the equation:

Volume x specific gravity = mass

Lets's use your given in our new equation:

10.0 mL x 1.04 = mass
10.4 = mass

The mass of a 10.0 mL sample of urine with a specific gravity of 1.04 is 10.4g.

A sample of gas occupies 6 ml at stp. at what pressure would this sample occupy 500 ml if the temperature is changed to 525◦c? a
Vika [28.1K]
From  the  combined  gas  law
that  is P1V1/T1=P2V2/T2
P2  is  therefore T2P1V1/TIV2
A  gas  at  STP has   a temperature of  273k and  a  pressure of  760torr
 P1=760torr
T1=273K
V1=6ml
P2=?
T2=525+273=798K
V2=500ml

P2 ={(798k  x760 torr x 6ml) /(273k x500ml)} = 26.7 torr
