Clearly, movement can be seen when I touch an object and apply a push or a pull. However, there are forces that can act at a distance. What are they?

Mass of tin sample

is ≈ 95.7g

Explanation:

This problem bothers on heat calorimetry/capacity of a substance.

Given data

Specific heat capacity of tin

Cp = 0.227 J/g•°C

Initial temperature of tin θ1= 15°C

Final temperature of tin θ2= -10°C

Heat released Q= 543 J

Mass of tin m=

We know that quantity of heat is given as

Q=mcΔθ

Substituting our given data and solving for mass m we have

543= m*0.227*(-10-15)

543= m*0.227*(-25)

543= - 5.675m

m=543/-5.675

= -95.68

Mass of tin is ≈ 95.7g

What is Quantity of heat?

Quantity of heat is the amount of heat absorbed or given out by a body Q=mcθ
