A substance of mass 200g measures 50cm*4cm*8cm. Calculate it density giving your answer in SI unit​

Physics
1 answer:
Oduvanchick [21]2 years ago
5 0

Answer:

0.2kg/0.0016m^3

Explanation:

200g is 0.2 kg

50*4*8 is equivalent to 1600 cubic centimeters which is also equivalent to 0.0016 cubic meters.

The SI unit for density is kg per cubic meter

So now we have 0.2kg/0.0016m^3

I hoped this helped, and if it did please give me brainliest

What is the relationship between matter and energy as it changes states of matter (phase changes?)
AlekseyPX

These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. The example we will use here is ice melting into water.

Pleaseeee Please help, I will love you forever and ever
matrenka [14]

Answer:

The answer to your question is

Explanation:

Data

mass = 0.5kg

T1 = 35

T2 = ?

Q = - 6.3 x 10⁴ J  = - 63000 J

Cp = 4184 J / kg°C

Formula

                        Q = mCp(T2 - T1)

                         T2 = T1 + Q/mCp    

Substitution

                       T2 = 35 - 63000/(0.5 x 4184)

                        T2 = 35 - 63000/2092

                        T2 = 35 - 30.1

                         T2 = 4.9 °C
