Substance A has twice the specific heat capacity as substance B. If 1000 J of heat are added to 1.0 kg of each substance, compare the change in temperature of each substance.

Answers

Substance A would have a delta T (change in temp) rise 1/2 the rise in substance B.

Q=mc x delta T

Q= heat energy in Joules
m= mass of substance heated or cooled
c= specific heat
ΔT is change in temp.

Solve for change in temp=. Q/mc

Specific heat and mass are not inversely proportional to heat energy input.

Putting into real world scenario of using water to heat a building.

Specific heat of water is 1.
It takes 1 btu to raise one pound of water 1 degF. at a base of 60 degF

Acetone specific heat is .51

So it takes half the amount of heat input to get a 100 degree ΔT, as compared to water.

The momentum of a 5-kilogram object moving at 6 meters per second is-

Answers

I think the answer is 30 but I’m not sure

The momentum of an object is 30 kgm/s . This can be calculated by using momentum formula see description below.

What is momentum?

It is defined as the product between mass and velocity. Its symbol is p.

It is given by:

p = m * v

What information do we have?

Mass = 5kg

Velocity = 6 m/s

To find:

Momentum=?

On substituting the values:

p = m * v

p =5 kg * 6 m/s

p = 30 kgm/s

Thus, the momentum of an object is 30 kgm/s.
