Answer:  Physical Properties

Explanation: Physical Properties are the properties which can be observe through naked eyes.

Chemical properties are the properties which induces any chemical change in the identity of the molecule.

Physical properties include color, smell, texture etc which can be easily observed but chemical properties include mass, volume reactivity which can only be observed when any changes in the chemical identity of the substance takes place.

Vinvika [58]

Answer:

83°C

Explanation:

The following were obtained from the question:

M = 40g

C = 4.2J/g°C

T1 = 91°C

T2 =?

Q = 1300J

Q = MCΔT

ΔT = Q/CM

ΔT = 1300/(4.2x40)

ΔT = 8°C

But ΔT = T1 — T2 (since the reaction involves cooling)

ΔT = T1 — T2

8 = 91 — T2

Collect like terms

8 — 91 = —T2

— 83 = —T2

Multiply through by —1

T2 = 83°C

The final temperature is 83°C
