Explanation:
Let's first start by mentioning the specific heat of air at constant volume. We consider constant volume and NOT constant pressure because the volume of the room remains constant while pressure may vary.
Specific heat at constant volume at 27°C = 0.718 kJ/kg*K
Initial temperature of room (in kelvin) = 283.15 K
Final temperature (required) of room = 293.15 K
Mass of air in room= volume * density= (4 * 5 * 7) * (1.204 kg/m3) = 168.56kg
Heat required at constant volume: 0.718 * (change in temp) * (mass of air)
Heat required = 0.718 * (293.15 - 283.15) * (168.56) = 1,210.26 kJ
Time taken for temperature rise: heat required / (rate of heat change)
Where rate of heat change = 10000 - 5000 = 5000 kJ/hr
Time taken = 1210.26 / 5000 = 0.24205 hours
Converted to minutes = 0.24205 * 60 = 14.52 minutes
Driving alone without the distraction from passengers reduces the risks you face in driving.

Explanation:
Dowry is a social evil in the society, that has caused unimaginable tortures and crimes towards women. The evil has taken lives of women from all stratas of society - be it poor, middle class or the rich. However it is the poor who succumb and fall prey to it, more due to their lack of awareness and education.
It is because of the dowry system, that daughters are not valued as much as the sons. In the society, many a times it has been seen that they are seen as a liability and are often subjected to subjugation and are given second hand treatment may it be in education or other amenities.
Today the government has come up with many laws and reforms, not only to eradicate the dowry system, but also to uplift the status of the girl child by bringing in many schemes.
It is now for the society at large to become aware and understand the situation. It up to all of us to take active steps in bringing about the necessary change and stop either giving or taking dowry. We must all know that we should start valuing our daughters first, so that others know their value once they grow up.
