A 275 g sample of a metal requires 10.75 kJ to change its temperature from 21.2 oC to its melting temperature, 327.5 oC. What is
Vlada [557]

Answer:

c=0.127\ J/g^{\circ} C

Explanation:

Given that,

Mass of the sample, m = 275 g

It required 10.75 kJ of heat to change its temperature from 21.2 °C to its melting temperature, 327.5 °C.

We need to find the specific heat of the metal. The heat required by a metal sample is given by :

Q=mc\Delta T

c is specific heat of the metal

c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{10.75\times 10^3\ J}{275\times (327.5 -21.2)}\\\\=0.127\ J/g^{\circ} C

So, the specific heat of metal is 0.127\ J/g^{\circ} C.

Explanation: I hope this help my child UwU

What is the weight of the ethyl alcohol that exactly fills a 200.0 mL container the density of ethyl alcohol is 0.789 g ml?

Density review

A

B

What is the weight of the ethyl alcohol that exactly fills a 200.0 mL container? The density of ethyl alcohol is 0.789 g/mL.

g = (0.789 g/mL) (200.0 mL) = 158 g

Match the name of each gas law to the properties it compares. 1. Gay-Lussac's law 2. Boyle's law 3. Avogadro's law a. Volume and
oee [108]

Answer:

1. C    2. B     3.  A

Explanation:

1. Gay- Lussac law, states that as along as the volume is kept constant, the      pressure of a fixed mass of gas is directly proportional to the temperature.

The properties it compares is; (c.) Pressure and temperature

2.  Boyle's Law states that; as long as the temperature is kept constant, the volume of a fixed mass of gas is inversely proportional to the pressure.

It therefore compares; (b.) Pressure and volume

3. Avogadro's Law states that equal volumes of different gases contain the same number of molecules provided the temperature and pressure are the same.

It therefore compares;  (a.) Volume and moles
