Answer:

The answer will be 2.98K

Explanation:

Using the formula:

Q = mc∆T

Q= 5,800 (heat in joules)

m= convert 15.2kg to g which is 15200g (mass in grams)

c= 0.128 J/g °c (Specific heat capacity)

∆T=  what we need to find (temperature change)

5800J = 15200g x 0.128 x ∆T

= 2.98K

What properties of matter explain why the weight of an object on the moon is different than the weight of the same object on ear
algol13

Answer:

Gravity explains this.

Explanation:

Weights and mass are different terms .

Weight is defined as the force exerting on the surface due to the mass and gravity of acceleration.

W=m*g

Here mass is related to the density of the body. So as the density would be same mass woulnt vary.

Whereas the Gravity changes due to the property of the planet.

Gravity is different for different planets and hence moon and earth have two different values.

So the mass i.e density remains same on both planets but the g value always changes hence weight is different.

HELP ASAP!!! How many grams of lead are in a 41.2 gram sample of lead (II) oxide? With work please :)
Afina-wow [57]
That would be 58.6 oxide because if the 41.2 plus the oxide would be 48 plus the other particcles inside it so it equaled 58.6 oxide
