Ans: C

Temperature can be expressed in terms of :

Kelvin (K), Celsius (C) or Fahrenheit (F)

The three units are interchangeable.

1) Kelvin(K) and Celsius(C)

K = 273 + C ----(1)

2) Celsius(C) and Fahrenheit(F)

F = (C*9/5) + 32 ---(2)

Option C is correct because:

From eq(1), when C = 100

K = 273 + 100 = 373

From eq(2), when C = 100

F = (100*9/5)+32 = 212

A piece of hot metal is put into an equal mass of water. The water temperature rises 5o and the metal’s temperature drops 10o. W
Mice21 [21]

Answer:

The answer to your question is     Cm = 2.093 J/kg°C

Explanation:

Data

mass metal = mass of water

Δ water = 5°

Δ metal = 10°

Cm = ?

Cw = 4.186 J/Kg°C

Formula

              for metal       for water

               mCmΔTm  = mCwΔTw

Cancel mass of metal

                  Cm ΔTm  =  CwΔTw

solve for Cm

                         Cm = (CwΔTw) / ΔTm

Substitution

                         Cm = (4.186 x 5) / 10

Simplification

                         Cm = 20.93 / 10

Result

                         Cm = 2.093 J/kg°C

A____H means that energy is ____<br> from a reaction.
ExtremeBDS [4]

<u>Answer:</u>

<em>A  negative ∆H means that energy is given off  from a reaction </em>

<em></em>

<u>Explanation:</u>

2NO_2 (g)N_2 O_4 (g)\\\\\Delta H=-58 KJ per mol

If the reaction has negative ∆H value then the reaction is exothermic

N_2 O_4 (g)2NO_2 (g)\\\\\Delta H=+58 KJ per mol

If the reaction has positive ∆H value then the reaction is endothermic

When Heat energy is given in the equation itself

If it is present on the left side it means that heat is absorbed and the reaction is Endothermic

If it is present on the right side it means heat is given off and the reaction is exothermic
