Answer:
10425 J are required
Explanation:
assuming that the water is entirely at liquid state at the beginning , the amount required is
Q= m*c*(T final - T initial)
where
m= mass of water = 25 g
T final = final temperature of water = 100°C
T initial= initial temperature of water = 0°C
c= specific heat capacities of water = 1 cal /g°C= 4.186 J/g°C ( we assume that is constant during the entire temperature range)
Q= heat required
therefore
Q= m*c*(T final - T initial)= 25 g * 4.186 J/g°C * (100°C- 0°C) = 10425 J
thus 10425 J are required
Answer:
Explanation:
Inquiry making is one of the methodical approaches to scientific investigation. Inquiry basically deals with asking question and querying a certain procedure or observation. In almost all the phases of a scientific investigation, the scientist will not cease to keep on asking questions that are connected to the observations and how this can help to further broaden the scope of the experiment. In fact, every investigation in science is an inquiry into a phenomenon and this generates series of questions that need to be satisfied.
