Charle's law gives the relationship between volume and temperature of gas.
It states that at constant pressure, volume of gas is directly proportional to temperature of gas.
V/T = k
where V - volume , T - temperature and k- constant 
\frac{V1}{T1} =  \frac{V2}{T2}
parameters for the first instance are on the left side of the equation and parameters for the second instance are on the right side of the equation 
T1 - 7 °C + 273 = 280 K
substituting these values in the equation 
\frac{49 mL}{280K} =  \frac{74 mL}{T}
T = 423 K
temperature in Celcius scale - 423 K - 273 = 150 °C

A metal hammer has been lying in the sunlight on a hot day. When you pick up the hammer, it feels very warm in your hand. Can yo
tangare [24]

Answer:

When the hammer is in the sun, heat flows by radiation

When you pick up the hammer, heat flows by conduction

Explanation:

As the hammer lies in the sun, heat is transferred to the hammer by radiation. Heat energy reaches the earth from the sun by radiation. Radiation is a mode of beat transfer in which heat is transferred without a material medium.

When you pick up the hammer, heat flows to your hand by conduction because your body is a conductor of heat.

What role does hydrogen bonding play in liquid water and ice?
Leto [7]
Due to hydrogen bonding there is a formation of cage like structure called lattice in ice due to which <span> density of ice is less than that of water. Moreover, it is a known fact that density of water is maximum at 4°C.</span>
