<h3>Answer:</h3>
Water molecules have a polarity, which allows them to be electrically attracted to other water molecules and other polar molecules by weak chemical bonds known as <u>Hydrogen Bond</u>.
<h3>Explanation:</h3>
Hydrogen Bond Interactions are those interactions which are formed between a <em>partial +ive</em> hydrogen atom bonded directly to most electronegative atoms (i.e. Fluorine, Oxygen and Nitrogen) of one molecule interacts with the <em>partial -ive</em> most electronegative atom of another molecule. These interactions are considered the strongest intermolecular interactions and are responsible for many stronger physical properties of water like, boiling point, viscosity, solubility e.t.c.
Attached figure shows the hydrogen bond interactions (green dashed lines) between water molecules. The partial charges are shown in red color.
we can do soo by noticing any colour change, or by the formation of an insoluble precipitate or by the evolution of a gas.

Explanation:
// C++ program to print initials of a name
#include <bits/stdc++.h>
using namespace std;
void printInitials(const string& name)
{
if (name.length() == 0)
return;
// Since touuper() returns int, we do typecasting
cout << (char)toupper(name[0]);
// Traverse rest of the string and print the
// characters after spaces.
for (int i = 1; i < name.length() - 1; i++)
if (name[i] == ' ')
cout << " " << (char)toupper(name[i + 1]);
}
// Driver code
int main()
{
string name = "prabhat kumar singh";
printInitials(name);
return 0;

Answer:
6 Watts
Explanation:
From the question given above, the following data were obtained:
Current (I) = 0.05 A
Voltage (V) = 120 V
Power (P) =?
Electrical power is defined by the following equation
The power consumption while the TV is in standby can be obtained as follow:
Power (P) = Current (I) × Voltage (V)
P = IV
With the above formula, we can obtain the power consumption while the TV is in standby. This can be obtained as follow:
Current (I) = 0.05 A
Voltage (V) = 120 V
Power (P) =?
P = IV
P = 0.05 × 120
P = 6 Watts
Therefore, the power consumption while the TV is in standby is 6 Watts.
