Why is 1T more easy TO wash soft water than
with hard! Because soft water unitcs free
~ with soap and dissolves it, instead of de-
composing it rs hard water does.
Why do wood ashes make hard water soft2
lst, Because the carbonic acid of wood ashes
combines with the sulphatc of lime in the
hard water, and converts it into chalk 2d
wood ashes also convert SONIC Of the soluble
salts ofwater into insoluble, and throw them
down as sediment by which the water re-
mains more pure.
Why has rain water such an unpleasant
smell when it is collected in n rain tub or
tank? because it is imprcgnatcd with dc
composed organic matters washed from the
roofs, trees, orthc casks in which it is col
lcctcd.
How docs blowing hot foods make thcm
cooi? 1t causes the air which has been heat
ell by food to change more rapidly, and give
place to fresh cool air.
Why do ladies fan them selves in hot wca-
thcr? That fresh PARTICLES of air may be
brought in contact with their face BY the ac-
ton of the fan; and as every fresh particle
OF air absorbs some heat from tho skin, this
constant change makes them cool
Docs fan cool the air? No. it makes the
air hotter, by mparting. 20 it the heat from
our face: but it c0ols our face by transfer
ring its heat to the air.
Why is there always n strong draft under
the door and through the crcviccs ON each
side? Because cold air rushes from the hall
to supply the void in the room caused by the
cscopc of warm air up the chimney &c.
Why Is there always strong draft tIrou oh
the kcyhole Of a door2 Because the air i'm
the room we ocnpy is warmer than the mir in
the hall therefore the air from the hall
rushcs through the kcyholc into the room,
and causes n draft.
Why is there always draft tlrou oh the
window crcyices? Because the external air,
being colder than the air Of the room VIC oc-
cupy. rushcs through the window crevccs to
supply the deficiency caused by the ccscapc of
the warm air up the chimney.
Ii you open the lower sash of q window
there is more draft than if you omen the up-
per sash. Explain tho reason of this. 1.-THE
lower sash be open, the cold external mir will
rush freely into the room and cause a great
draft inward; butt the upper sash he open,
the heated air of the room rushcs out, and
of course, there will be less draftinward.
Why is a room best ventilated by opening
the upper sash Because the hot vitiatcd
air, which always asccnds toward the ceiling,
can escape more easily.
BY which means is hot room moro quick
y N'c'SN tiC upper OF lower
sash n hot room is COOLED more quickly
by opening the lower sash, because the out
or air can enter more freely into the lower
part of the room where it is colder.
Why does the wind dry damp linen? Be-
cause dry wind, like a dry sponge, imbibcs
the particles of vapor from the surface of the
linen as fast as they are formed.
Which is the hottest place ina church or
chapel? The gallery.
Why is the gallery of all public places hot
ter than the lower parts of the buildings :?
Because the heated air of the building as
cends, and all the cold air which can enter
through the doors and windows keeps to the
aocr t!l 1t hos become heated.
