Here are some of the characteristics of a mixture:

  • Composition is indefinite i.e they consist of two or more elements and or compounds in any proportion by mass
  • The constituents retain their identities i.e physical properties are not altered.
  • The constituents reacts differently to changed conditions.
  • They can easily be separated into constituents by physical methods.

An aluminium kettle weighs 1.05 Kg.
Kipish [7]

Answer:Explained

Explanation:

Given

mass of aluminium kettle(m_k)=1.05 kg

(a)Heat capacity of the kettle=Heat capacity of Aluminium

C_{Al}=0.9 J/gm-K

(b)Heat is required to increase the temperature of this kettle from 23^{\circ} to 99 ^{\circ}

Q=m_kc_k\Delta T

Q=1.05\times 0.9\times 1000\times \left ( 99-23\right )

Q=71.82 kJ

(c)If kettle contains water 1.25 L of water i.e. 1.246 kg of water then heat required to raise the temperature from 23 to 99

Q=m_kc_k\left ( \Delta T\right )+m_wc_w\left ( \Delta T\right )

Q=1.05\times 0.9\times 1000\times \left ( 99-23\right )+1.246\times 4.184\times 1000\times \left ( 99-23\right )

Q=71.82+396.20=468.028 kJ
