Summ. labs


we learnd that there is 100cm. in 1m.for volume we learnd that sometimes when two things have different size mulicals the smaller ones take up the lost space in the bigger mulicals. to measure volume we do HxWxL

in this lab we were trying to find the mass and volume []

when we put the car down the ramp it started to turn on its own so we used a meter stick to keep i strait. tempoture metal- felt the coldest cardbord-warm rock-cold plastic-neutral plastic foam-warm wood-felt the warmest

hand can't measure temp. because it can only sence heat

heat:transfer of energy bettween objects that are differant tempotures

tepoture is a measure of the average kinetic energyof the pparticals in an odject.( thermal energy is the total kinetic energy of particals temp. is average.)

thrmal equalibrium there is no change in temp.

test subject which tub of water is the warmest

ZACK B EDDIE B tub 20.8 tuba 21.6

the temperture was 40oC it was closer to the hotter temperture which was 80. the average temperture was always alittle higher than the mixed temperture in order to not loose energy []
