Use the particle theory of matter to explain why laundry detergents tend to work better in hot water than in cold water.

Particle theory of matter states that particles at higher temperatures move faster that those at lower temperatures. Then laundry detergents particles move faster in hot water than in cold water, and therefore, they are more efficient and work better.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

did anyone actually do this? like if anyone has submitted this i rly need .
