A sample of aluminum, which has a specific heat capacity of 0.897·J·g−1°C^−1 , is put into a calorimeter (see sketch at right) t
Tcecarenko [31]

Answer: The mass of aluminium sample is 55.4 gram

Explanation:

Q_{absorbed}=Q_{released}

As we know that,  

Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})

m_1\times c\times (T_{final}-T_1)=-[m_2\times c\times (T_{final}-T_2)]      

where,

m_1 = mass of aluminium = ?

m_2 = mass of water = 300.0 g

T_{final} = final temperature = 23.8^0C

T_1 = temperature of aluminium = 94.5^oC

T_2 = temperature of water = 21.0^oC

c_1 = specific heat of aluminium = 0.897J/g^0C

c_2 = specific heat of water =  4.184J/g^0C

Now put all the given values in equation (1), we get

-[m_1\times c_1\times (T_{final}-T_1)]=[m_2\times c_2\times (T_{final}-T_2)]

-[m_1\times 0.897\times (23.8-94.5)^0C]=[300.0g\times 4.184\times (23.8-21.0)]

m_1=55.4g

Therefore, the mass of aluminium sample is 55.4 gram

A student is shown a simple model of particles that make up a liquid,as shown.
trapecia [35]
Answer:
            Option-D : <span>Decrease the velocities of the particles, and decrease the space between the particles.

Explanation:
                     The solid state of matter is composed of particles closely packed with a minimum space between them. This closed packing of particles occur due to strong interatomic or intermolecular interactions between particles. Therefore, solids particles have zero translational and rotational motions and only show vibrational motions. So, decrease in velocity and decrease in space between particles is the right answer for making solids.</span>
